I went back to have another look - i had the same experience where i couldn't see the UC tables in any tool that used the oauth connection type (back in early sept) - but tried it again just now and i can see UC tables again in access

Which endpoint are you connecting to? I'm using sql warehouse classic

Did you try using a PAT instead of oauth?

I dont really have any other suggestions, sorry
