Online library not syncing

I am working in the Zotero app currently and the changes I make are not syncing to the online library (group library). The last sync was 5 days ago and when I click on the sync button, it doesn't do anything. I checked if it was connected to the right library and it is, so that doesn't seem to be the problem.
for example: I transferred an article to another map, but in the online library it doens't become visible, the debug ID is: D1865910196
