I’ve been having this same issue.
At first I wasn’t able to watch certain shows/movies, but was able to watch others. Then last night, I really wanted to watch a certain show that wasn’t working…so after an update & restart had no effect, I deleted & reinstalled the app.
Now, from the very beginning, when I click the “sign in or sign up” option, it just buffers forever. So I don’t think it has anything to do with my specific Apple + account…since the trouble starts before I even sign in.
I’ve seen your response on several different threads with ppl having this type of issue, & after trying all the usual things, I’ve come to believe it does have something to do with my Spectrum router & Apple TV +.
I haven’t customized anything, at least not on purpose…(I’m not tech savvy AT ALL), I don’t even really know what a router is/does.
So my question is, how do I verify whether or not the ports Apple services like to use are being blocked? Is that something I look up in settings, or do I need to call Spectrum?
Idk what DNS or ISP means in the slightest, so I just have to hope it doesn’t have to do with those things.
If I didn’t want to watch Monarch so badly I’d have already deleted the app & service altogether. Lol
