New Zoom Feature allways removes like it's never been

Hi everybody,
Ever since the zoom feature was introduced, I’ve repeatedly encountered a phenomenon where the feature—despite having been present—suddenly disappears. There is no slider, no zoom option in the ribbon, and no corresponding database options. I am using Microsoft® Access® for Microsoft 365 MSO (Version 2609, Build 16.0.20430.20032, 64-bit) on the Monthly Enterprise Channel. Following an update to this version, the feature reappeared. I opened several databases, and the slider was visible—it worked without any major issues (even though I rarely use it), with no crashes or error messages. Then, upon opening another database, the slider and all other elements related to the zoom feature vanished. When I went back to the previous databases, the feature had disappeared there as well. Restarting the PC and performing a "Quick Repair" had no effect. I have observed the same behavior across the previous five versions; the feature keeps disappearing. It seems that a new "Click-to-Run" update might re-enable it (though I’m not entirely certain). Something—or someone (Microsoft ?)—is disabling it. Fortunately, I haven’t incorporated this new feature into any of my objects or VBA code yet; otherwise, the database would crash! Does anyone have any ideas?
