Over at WA we received a help desk ticket from DCS user Tada. (s)He has been having trouble uploading since upgrading to version 1.6.0 of BTT-Writer Android. I have no contact information for this user, and so can’t provide assistance directly.
The two most likely causes are 1. changes in the way 1.6.0 connects to gitea (user agent, for example) and 2. changes made to DCS in the last month.
I’m happy to help track this down.
