iOS upload 95.4 mb stopped

Ios app upload stops after 95.4 mb displayed. I tried several hotels wifi. I tried to uninstall, reboot. Re-install the app. There is enough space on the iphone and on the server connected. Smaller photos or videos get uploaded with no time and no issues. It is a core functionality. 95.4 mb is a very small video these days, almost nothing. It renders my main reason why to use nextcloud useless.
(Not a save home in terms of stability.)

I confirm i have read the post iOS app fails uploading larger files than 100MB but this did not resolve my problem at all.

Server version update to “stable” channel 31.0.0, did not change the issue. Ios 18.3.1 most up to date version at the time of writing. No pending updates in ios app store for this app 6.3.0.11 hydrogen).

I have the faint impression that nextcloud is too pushy on new stuff and compromises stability (of core functionality) in the last few years (while i had used and appreciated the stability all these years), if you permit this remark.
