Why do I get error "Writing Tools is unavailable" when opening Apple Intelligence?

Please Help Writing Tools Unavailable - Certain capabilities are unavailable at this time. Try again later.

I've been trying over the last 2 days, and I keep getting this message:

Writing Tools Unavailable

Certain capabilities are unavailable at this time. Try again later.

This error pops up for the following options: Summary, Key Points, List and Table

The error appears in Notes, TextEdit, Safari and Mail.

I've restarted my Mac countless times and turned Apple Intelligence off and on, but I still get the error.

Is there anything I could do to fix this? When I searched for the error, I saw some were experiencing the issue during the 15.1 beta but could not find a solution. I don't know if the problem is on my side or Apple's.

The Writing Tools work fine on my iPhone 15 Pro Max.

My computer is a 16" MacBook Pro M1 Max with 32 gigs of memory.

Does anyone know where I can report this issue directly to Apple?

I understand Apple Intelligence is in beta, but how and where do I report issues?

Thank you!
