Copy/Paste of diagrams in Google docs/presentation stopped working by a few days

I am alone noticing that you can't anymore copy/paste slides between presentations or diagrams between different google drive documents

It's interesting to watch Google's quality of service going downhill pretty much across the board. I used to be surprised at even smallest bugs; now I cannot sign in to Google Play console without going through Incognito Tab, and it's just par for the course.

Just tried it, it works for me.

A result of them moving to Flutter?

Soon to hit the graveyard ?

I had no issue with that, but slides kept "losing" my figures while it was open - it got quite frustrating since I was trying to record a talk.
