Universal clipboard not working

when I copy some text on my iPad (Air, latest ipadOS) and paste it in Drafts on my iPhone (latest iOS), I have the screen message “Paste from iPad” with the working wheel, but then nothing is pasted! Same from iPhone to iPad.
I can paste from iPad to iPhone in the Notes app, or elsewhere, but not in Drafts.
Do you experience this issue too ?

Working fine for me copy-pasting from browser on iPad into Drafts on iPhone.

Does the issue persist for you after restarting both devices?

Yes it does. And weird, I paste on Notes, it’s ok. Then right after this, I paste on Drafts : nothing. When I paste on a text selection, the selected text is deleted.
