This is probably an ONLYOFFICE issue, but trying here first since it I am accessing it through Nextcloud.
I have a few cells that have a formula, but after I save, exit and reopen, the formula changes to =#NAME?. I then redo the formula, but the same thing happens when I reopen.
These cells in question are referecning other cells who also have a formula - not sure if this has anything to do with it. As an example:
D1 would be the cell that gets changed to =#NAME?.
Has anyone else seen this before?
