I installed lately google sheet extension pro , but I face a big problem
the free google sheet api disapeared from the menu
all the blocks made with it were deleted
and the most
the extension is not working
could you advise me how to come back to the free google sheet api and show it in the storage menu?
What do you mean by "storage" ?
You do not need a paid extension to access google sheets, there are several free extensions and non extension methods to be found on this community that will serve you well, or simply use the spreadsheet component.
