Business user here. I didn’t get an answer at discussions@apple so now I am here. I use iCloud for my law office, every client folder has its own Numbers file so it’s at least hundreds of .numbers files that are affected and interfere with my daily work in a devastating way.
Problem is there since some months, another new problem since some 1-4 weeks. Only .numbers files that are on iCloud AND shared to other people (everyone with link / read only) are affected. it is independent of MacOS and device, I have quite a lot of Mac Minis and Macbooks.
This is what happens to -all- of the above mentioned .numbers files:
Their contents are not searchable anymore. This is horrible for me, I rely on numbers values and formulas that give out certain strings that need to be findable with finder or spotlight search. They get only searchable again if I copy the single .numbers file to a non shared place on iCloud AND open, edit anything and save and close them. Only workaround which is horrible for my office.
Alternatively ".nosync" in filename helps too.
Since some weeks: When opening the .numbers files (which is saved on the ssd, so no cloud download necessary) a loading bar of numbers app appears, which takes 10-40 seconds to open one single .numbers file. This destroys my whole workflow. interestingly when going offline and opening the numbers files it opens as usual in miliseconds although this "numbers is offline" pop-up appears.
Problems disappear as soon as I deactivate file sharing and edit & save the numbers files once. So it is reproducible. Sidenote: Other shared files are not affected and are searchable. I don't use .pages files though.
Problem persisted even after changing the MacBook. For general info, I use a MacBook Pro 2023 M3 Pro chip. Latest macOS and .numbers updates.
