Why does Öffis build 140007 in F-Droid repo (started Thu Jul 23 20:41:37 UTC 2026) which succeeded AFAICS, not appear on Offi | F-Droid - Free and Open Source Android App Repository resp. in the app?
The newest Öffi version 14.0.7 fixes an API-key problem (hint shown on startup in version 14.0.6). The update is necessary to use the DB provider.
