Info disappeared from grouped column?

Today I entered two paragraphs of important notes into a grouped column within a table and when I finished typing, the paragprahs disappeared! I tried to ‘Undo’ and view doc history but it doesn’t seem to acknowledge that I had been typing in about two paragraphs worth of stuff at all. Is there anyway to recover it and/or figure out what happened?? I’ve ungrouped the column and what I was typing still doesn’t show, plus I don’t see anything hidden

Wow! That’s a huge bummer. Is there any way you can give more context? What do you mean “typing into a grouped column”

Can you give the exact circumstance and maybe a screenshot to show where you were typing?
