Could be. I've noticed my iPhone started to accidentally intermittently lose WiFi connection, only to reconnect again in ~3-5 seconds. I wasn't sure if this is iOS or UniFi AP bug, but I suppose it could be the former.
To add anecdata, I've been seeing the subject behavior on Meraki equipment across various firmware versions. I'm inclined to think this is an Apple-initiated issue.
As it happens, I'm also on a Unifi AP, so that's curious. Would not hesitate to assign blame there... Although, I have long since abandoned their automatic firmware updates which has really helped with stability, so I'm not sure what would've changed on the AP _recently_.
