Hi, I just learned in this topic (Nextcloud Android App Version 3.32 - Automatischer Fotoupload "Lokale Datei nicht gefunden" / Auto Upload: Local File not found - #4 by maziarz189) that there is another setting you have to set. It is not enough to set access to “all photos” in the access tab of the Nextcloud app. You also need to register the Nextcloud app in this menu :
Settings > Apps > Special app access > All files access
Tested and automatic upload works (again) on Moto G75 and G54.
I was not aware of this setting until today… (when Maziarz189 hinted me that way!)
