Sure there must, however if you expect help, your “story” kind of lack , info in regards to logfiles, your which system you are running, etc. etc.
Or people ( as me ) will just “shoot in the dark”
Im sure you have read about people having issues with i.e their “wifi” etc, and people with alot device communicating through the cloud ( brand specific devices/clouds ) … this would/could give the same “result” under certain circumstances.
How to help us help you - or How to ask a good question.
To your initial “direct” question … No i have not experience the behavior you describe, and i have also updated to latest few days ago, and added another 2-3 wifi devices to HA ( so im closing up on 40 wifi-device, spread widely, on 2 floors + basement, Garage
PS: I forgot to mention about the increasing DB and Logfiles issues some people experience, which slow down and even hang/crash HA … because people don’t check their log files
