We have tables in our ClickUp Docs and there doesn't seem to be a way to edit those tables within the CU Docs on mobile.
Viewing a CU Doc on mobile also is a little difficult because it's not responsive to a smaller screen, it just stays big. Would be great to be able to adjust that if needed.
And lastly, when viewing a CU Doc on mobile, there is some information that stays pinned to the top of the window within the Doc, but it covers the text of the Doc beneath it.
