I did the latest update on my iPhone and all my contacts are getting a message on their chat window when I call or message them.
"Perfect Forward Secrecy has been disabled in this conversation because your chat partner's app version doesn't support it."
I am not sure why this happened.
Is there any settings to make this PFS active?
Thanks!
I installed Threema on my Samsung A50 phone using the license bought from Threema Shop
I am getting the message, update available. I click continue and later getting this message. "Threema cannot update"
Am I missing any settings to proceed with the update within the app /within the phone settings? 
Whenever I install Threema on my phone, I am getting a new ID every time. This is is generated by swiping the ID generator code during install
Does this ID is verified by the Threema server?
Millions of Threema users around the world and is there any chance for a duplicate ID within Threema installs/users?? (
That's good news..
I experienced similar issues on my iOS 14.3 few times..
Whenever I pick an incoming call, it disconnects and the calling party on the other end cannot listen anything. Then they try to call again gets the busy message.
Is there any settings need change on my iPhone?
Thanks
Any news on discount offers from Threema shop this year?
Something like this?
I think this is OS specific.
Other messaging apps on iPhone doesn't show the profile picture either...
See the difference below
Android:
iPhone:
When I receive a message from a contact on my iPhone, the message banner doesn't show the profile picture
But it shows on Android phone. Is there any settings or it's different on both versions 
You can only see it after your contact has written you at least one message.
I am getting messages from my contacts and still unable to see their profile pictures
Most of them use Android version and tried both options "everybody you write to" and selected contacts (enabled the contact)
Anyone experience similar issues or suggest any setting changes
I am unable to see the profile picture on my iPhone 10, from from other contacts
I asked my contacts to enable "Who can see my profile picture?" and still it's not visible in my Threema message
Am I missing any settings?
Thanks
When I add a contact ID, the verification level is 1 out of 3 (RED)
Does this matters for chat and voice call privacy?

Is it possible to add different colors for different conversations (similas to Signal)
This will have visual effect on different conversations and highlight between the incoming and outgoing messages
Thanks!

I bought Threema from google play store and installed on a phone.
I wanted to use Threema on a different phone.
Can I delete the ID from my first phone, uninstall Threema and install on my 2nd phone and transfer ID?
I this legally possible and how can i do this
Thanks

You're only every allowed to use one license on one phone at a time. But changing phones is fine.
I am not using the license on both phones. I like to delete ID from one phone and use on another android phone
The original one I downloaded from Playstore and if this transfer is possible, how can I install on the other phone.
Is this legal and permitted?
Thanks for your comments..
Do you expect any further improvements or added features coming to Threema in 2020
I just bought Threema for iPhone tried for couple of days and wondering what's the difference between Signal and Threema
I tried both these apps and couldn't find any major difference between the two
Both are secured and offers almost similar features (Threema even doesn't offer video call)
Can someone please comment and explain how can I recommend Threema to my other contacts and friends?
Thanks!
If I buy a license from Threema shop and install on my phone try for sometime (just for testing).
Later can I transfer this license to a different phone used by one of my friend?

Is it possible to get this in English?
Thanks!

I once took the trouble to put together tips and tricks for Threema. Where and what Threema can do. The instructions are for iOS and Android smartphones.
Is it possible to get the installation pdf in English?
Thanks!
True, apps purchased in Apple AppStore are not transferable to Android.
As far as I know, the only way to give Android users Threema is to sell and distribute licenses from the Threema store.
And this is how the installation works: https://threema.ch/content/threema_installation_de.pdf
In my experience, unfortunately, not too recommendable for technically less experienced users, since they a) are often overwhelmed with the installation of apps from .apk files (see instructions linked above), and b) at the latest when reinstalling on a new one Cell phone can no longer find the license key. It would probably be helpful if you could offer help with the installation ...
