Hi there,
I remember we fixed something that may be related to this just before releasing the 4.2 version (you can find the fix in this PR: moodlehq/moodleapp#3704).
It was related with a bug in Ionic for Chrome version 114 and newer, so this could have happened if you recently updated the webview engine. If it isn't that, I'm not sure what's the problem, we haven't heard of anyone else facing this problem.
