So in this case, this has actually been going on for a while - even before this. However, because this was the only significant change in my configuration, I thought it could have been due to this update. I was a beta tester for Kiosker Pro - so I had advanced access to this update as well.
There are a few threads, but this one captures most of what I was understanding:
Background network disconnected - Reload - SharpTools.io (web) - SharpTools Community
I have not created a Test Account - honestly I’ve just been “dealing with it” hoping for an iOS upgrade or something…
In regards to how it manefests itself:
Here, the dashboard is no longer “live”
Here, this is what I typically wake up to after overnight - but this happens randomly even during the day. Sometimes I can go 1-2 days, but eventually all three iPads will wind up looking like this - I didn’t get a good photo but the toast says “Socket Status Unknown” and there is a “loading” animation that just sits there.
As an alternative - I tried downloading Brave and making it the “default” browser - no help.
I bought “Kiosk Pro Plus” - no help
I bought “tKiosk” - no help
I tried “Kiosk - Fullscreen Broswer” - no help
I tried “URL Bookmark” / guided access - no help
What I haven’t tried yet is using Brave as a “bookmark” and guided access…
i did get this replay from Kiosker Pro:
“We are aware of memory leaks on some legacy devices. Our investigation points at memory leaks in the Apple WebKit engine. We have filed a bug report to Apple and they have responded that tey are aware of the issue. No solution is available at the moment. The issue seems quite hard to pinpoint since crashes only happens on some devices. We have a iPad Air 2 running a Home Assistant Dashboard for months without crashing.”
I owe them some logs - which I will be working on collecting…
