Yeah I don't doubt that. My phones and PC are always fine also. I use an ONN 4K device for the TV. The first month or two was ok. Then I updated the app at one point and it's never been the same since. I've uninstalled and reinstalled and changed to Projectivy and tried some other loaders as well, and the problem just keeps coming back. We'll see if this Wholphin client changes anything.
This sounds like your client-device is either aggressive in App Cache cleaning.
