After updating to the latest version yesterday, it doesn’t work anymore. The functions of the other tabs, not just the insert tab, are working and not working. I downgraded to the version I was using before, but the problem is the same, now it doesn’t work in any version.
I was having the same issue (on Windows). I have my files saved on OneDrive and I was thinking it was a drive problem, then i noticed i wrote this thing on my file:
linked photo
(it was red colored by the software);
I tried to cancel the thing and then the insert function restarted to work.
Hope this can help (:
