I'll make this my last comment for now until there's an update on the situation...
14-2-26
Google Pixel 6 on android 16 :
* No longer showing any previously loaded external avatars (so nothing from either Gravatar or Apistemic) - only lettered circles or icons I have from my Contacts.
* When I first updated A.M., the external avatars were showing up. All have disappeared, as above.
* I've cleared cache; force-closed / re-opened; left A.M. open for 10 minutes without scrolling - no difference.
UPDATE 15-2-26
I decided to uninstall & re-install the app on my Google Pixel 6 today. After tweaking settings again, I noticed...
* Some External avatars for those that do show up on the tablet, reappeared on the phone. Notably - trustpilot.com, perplexity.ai & google.com (googlealerts)... However...
On the tablet, aqua-mail.com, santander.go.uk, daddario.com, which.go.uk & thedebrief.com have appropriate avatars - but these refuse to load on the newly installed Aqua Mail on the phone, even after leaving the app open with these in view for ~10 minutes.
Samsung Galaxy Tab S4 on android 10:
* Previously loaded external avatars are showing still.
* No Avatars for common domains like PayPal, eBay, Apple etc have shown up (I assume these should be available from either Gravatar or Apistemic?) - only colored, lettered circles.
