Upload does not work anymore

[maffe]

After tapping on Hochladen, I get the following messages:

• SimRa Hochladen gestartet
• SimRa Hochladen fehlgeschlagen. Versuche es später erneut.

The last time it worked was for my rides on 2025-07-28. My rides from 2025-08-06 and later could not be uploaded. App version is 101.0 from Google Play Store.

It works again.

Today upload is broken again, same error message as before.

Closing since it seems to work recently.

[maffe]

Upload failed each of the last 4 days.

Two days ago it worked again, but maybe there is a way to make it more reliable?
