Library on App missing - Library online still visible
I've recently switched to a different MacBook and set up the Zotero App with synchronization. However, upon launching the App, I found my library missing. I've ensured that my sync settings are correct. My complete online library is still visible.To test out what is happening, I used the Zotero Chrome extension to add a new item to the library. This addition promptly appeared in both the online library and the App Library. As a result, the App library now only contains the latest few references I added for testing. I've followed the forum's recommendations to troubleshoot syncing issues, but the problem persists.
This doesn't really make sense, though. The app can't upload an item to the online library without downloading all the data first. In addition to the info requested on the linked page, can you take a screenshot that shows your local library, upload it somewhere (Google Drive, Dropbox, etc.), and provide a link here?

To be clear, the only confusing thing you said is "This addition promptly appeared in both the online library and the App Library", and you haven't shown any evidence of that.
Otherwise, the standard answer here is just that you either haven't set up syncing or you set it up with a different account. But you didn't provide the Debug ID requested on the linked page, so that's all I can tell you at this point.
