I can't seem to get Safari Connector to work with Zotero 7.0.26. At first I couldn't even find Safari Connector in the Extensions tab of Settings, but it did eventually appear—not after one restart, but after several restarts. But now that I see it and checked the box, it does not appear in my Safari window, i.e. it is unusable.

I'm running Mac OS Sequoia 15.6.1. I followed all of the instructions here: https://www.zotero.org/support/kb/safari_compatibility including 1) reinstalling the app; 2) compressing and uncompressing Zotero; and 3) forcing extension reloading. I restarted my computer after each of these steps. I'm running a 2020 MacBook Air with an M1 chip. Any suggestions appreciated.
