android: Unable to connect to Home Assistant

Home Assistant Android version: 2002.2 Android version: 9 and 11 Phone model: OnePlus, Pixel-3, Teclast Tablet and others Home Assistant version: 2021.12.8 Last working Home Assistant release (if known): Don’t know. Auto-update updated it sometime in the last couple of days, I assume. Description of problem: I am experiencing the following (which just started two days ago and has persisted):

• When launched, within a few seconds, the following message pops up:

Unable to connect to Home Assistant
Wait, Refresh External URL, Settings

• The page continues to load without apparent problems.
• If I click WAIT, or anywhere on the page, the message goes away but reappears several seconds later.
• All pages continue to work as expected, but no matter what lovelace page is showing, the message reappears. I have checked my SSL certs and restarted the server to no avail. Although I see other issues regarding connections, I did not see any with similar symptoms to this issue.
• I have force stopped the app and cleared the cache.

The identical problem is occurring on 8 different android devices.

Access to HA from Chrome directly has no problems.

I am running WebView 98.0.4758.101

Thanks for any advice/help…

P.S. I was running the latest Beta version, but downgraded to non-beta in the hope it would fix the problem.
