Unfortunately do to the variety of content creators and that they all charge fees Onlyfans is very hard to diagnose for users. One content creator may work another’s may not.
You can try the old fallback of clearing temp folders, cache and cookies etc, to see if that changes things.
If not uninstall and reinstall may fix.
If not then contact SF direct with a log a s see what they can do.
