I use DC since v0.5 from f-droid. Thanks for your good work.
Over time I had a strange problem with only a few, not with all chat partners.
Everthing works and suddenly “the encryption did not work anymore” or “message are not received at all”.
I think in case of “message are not received at all” this could be related to different versions, e.g. one chat partner used DC from google market and had newer version compared to version from f-droid.
Can somebody enlighten this situation out of his/her experience?
The second issue “the encryption did not work anymore” is more important - I’m still clueless and I’m not able to solve it.
So my main question would be: how to enable encryption again???
some more details:
chat partner use gmail.
last message succesfully encrypted is from beginning this year.
we did not have contact for a couple of month. if I write chat partner or vice versa, all messages are plaintext.
I updated to 1.12.0 and used the desktop client (the same with APK). Chat partner told me they always use latest version.
I removed and added the contact again. no difference.
Anybody has a explanation or clue?
