I need to copy a list to a sub-site on Sharepoint Online. Both use modern experience.
I tried the "save as a template" method, but the templates which are in the main site only work for the main site itself. I can see the templates as apps (intuitive isn't it?) that I can add to the main site, BUT they don't show up in the sub-site. And there's no template gallery at all for it.
I also tried to create a new list "based on an existing list", but that invariably fails (with no error codes, just "sorry, something went wrong. Try again later").
I tried to re-upload the saved templates (.stp files) into the sub-site by using the upload->template feature in the document library. But that seemingly does nothing.
(RANT: I think this is appalling, and it sure is frustrating to be searching around for 2 days in order to achieve something as simple as copying a DB.)
any suggestions? TA
