### Steps to reproduce
1. Use Google Pixel 3a with Android 10 / Android Q ROM
2. Install Nextcloud SMS from F-Droid forcing installation of incompatible versions (tested 2.0.4 and 2.0.5)
3. Execute, enter credentials and start sync
4. The application displays "Sync done" or something along those lines (my installed application is in French) after a couple of seconds
### Expected behaviour
ocsms application in Nextcloud instance should display new sync'ed messages
### Actual behaviour
messages don't show in ocsms application
### Server configuration
Synology DS218+
**Nextcloud version:**
14.0.4
**PHP version:**
7.0.33
**Webserver:**
nginx on Synology WebStation
**HTTPS:**
enabled
### Client configuration
**Android version:**
2.0.4 and 2.0.5 from F-Droid store
**Phone:**
Google Pixel 3a with Android 10 ROM
**Nextcloud SMS app version:**
2.1.6
### Logs
(could you tell me how to get those logs ? I don't see anything relevant in /var/log nor in /nextcloud/data/nextcloud.log)
## Screenshots
## additional info
The server-side configuration should be right because it worked as expected with my previous phone (Xiaomi Redmi 5 plus with Android 9)
