I have access to over 100 cameras from various models, I can watch them all without issues, except for the Tapo C520WS.

I got two C520WS and both have an issue with iOS - they make the Tapo app crash within seconds while watching the camera or the recordings. 

It does not happen when accessing the same cameras on Android devices. 

Everything (iOS, Tapo app, camera firmware) is updated to the latest version. This was tested with iphone 13 Pro Max, iphone 14 and iphone 15. They all crash the same way and they only crash while watching this specific model of camera.

Please work on a firmware update and/or an app update.
