I dont know that this is a login or connection issie, but none of the categories fits.
A week or so ago instead of opening normally, my Google Home app opens a small window that says I don't have access to the service. I can't see or access anything.
Nevermind. I got it. For some mysterious reason, it was using my college account (which uses Google)instead of my personal account No way to access the app to fix it, so I deleted my college account from my phone. Once it was gone, the app had no choice but to use the right account.
Pretty stupid way to fix a glitch, but at least it worked.
It looks like we have come to a solution so I'm going to be locking this thread. If you have any other concerns or questions, please feel free to create a new thread.
Have a great day.
