PWA frustrations:
They all disappear when you change homescreens.
I've bookmarked them all in a folder in Firefox Android, but then have to go through the whole add-to-homescreen dance again on any new homescreen

I have the Twitter PWA Starbucks PWA and a PWA of my own creation added and all are in my app drawer. Installed to my Pixel 3 from regular stable Chrome.

Hm, I installed Twitter and also one of my own. Twitter doesn't show up in app drawer (just the native app). Found that mine works as PWA in Firefox but Chrome Dev doesn't treat as PWA... so some compat error there maybe.

Loading seems to be taking a while.
Twitter may be over capacity or experiencing a momentary hiccup. Try again or visit Twitter Status for more information.
