Syncthing-android 1.18.6-rc.1.2 has just been accepted to google play as a beta release. In this release API level 30 is targeted, which brings changes to how the filesystem access works. One notable positive change is that SD card access is finally available on Android >= 11. Some not so nice changes (files being hidden) required a database reset on upgrade. There’s a wizard page on upgrade explaining that.
Please test the current beta release and report your experiences with it here.
Also please contribute translations for the information displayed on upgrade, such that we have as many as possible when on the stable release: syncthing-android localization
Thanks in advance
