Help Samsung Galaxy A10s - video calls no longer working


Hey gang, been a long time since I've needed help. I've got an issue since the last Android update around a month ago.

I'd been having video calls on a weekly basis, then the OS updated, and then the video calls no longer worked. We tried a couple of different video platforms, they all appeared as though they should be working (permissions, green lights, check marks, etc), but the video screen just wouldn't pop up.

Although we've been using my iPad ever since as a substitute, I'd really like to fix the issue with my phone. Thanks in advance.
