Apologies up front as Im not very techy. I have been trying to sign into and enable mycloud access on my device for a week with no luck. This is a second mycloud ultra on the same home network. When I to sign into my mycloud.com account from the device dashboard, it hangs on “updating”.
My other mycloud ultra – which is the original one – has no such issues. This original mycloud that works is connected to a different eero device, but on the same network.
First, I’d go back to previous firmware 5.26.300. The actual one is full of errors. If you still cannot access remotely, I’d make a 40 sec reset to rebuild the database (if you have albums, they will be deleted)
