SOLVED! @WillowMobileSys you were on the right track, accept I needed to clear data for the app (AppSheet Android app) not browsers.
Settings → Apps → AppSheet → Storage → Clear data & Clear cache
So the Android app must be a web app container that holds info like the browser. Anyway, I clear both the cache and the data, which deleted shotcuts I had set up, for both apps I use. I needed to go in again on the web view (Chrome), call up the apps and re-setup the shortcuts, but now they work fine, even when resized!!
