Slow with tables

Slow with tables

Notes with tables are really slow.

Even if I just wanted to change the column type, after clicking the "Column Type" button, the whole web seemed did nothing, it just waited there.

It also happend when I tried to delete the table.
Nothing happened after I click on the block button.
The tables can be draged, it is also possible to edit contents in columns.
But the tool panel seems...dead.

I tried the above things on Edge, Chrome and Android App (with a Android 11 device).
All of the issues are the same.

Please fix this problem, I just upgraded my plan to Pro because of the Black Friday Sale, 
but the experience is really frustrating .
