I have moved to a new location and, therefore, a new WiFi provider. My AppleTV seems to disapprove of this change and will not show the Main Menu or anything beyond that. It flips to a screen that shows the words "Main Menu" but nothing but darkness follows. It all worked beautifully before.
Suggestions?
Apple TV (4th generation)
Suggest you do a forced shutdown/restart:

I have done this and it has always cleared a freeze or the malfunction with the Apple TV.
The above link provides several ways to do this. One of them is to simply pull the power cord, wait 5-10 seconds, then plug in and start up again.
I haven’t got (or used an Apple TV) but I do have other streaming devices.
If you have your passwords for your channels etc. I suggest doing a factory reset. The link describes how.

Apologies: the link requires you to get into settings. Check the manual to see if there is a reset button or combination.
