Shortcuts disappear from Favs list

Thanks for the active development of this browser.

I have shortcuts that disappear (A17, Pixel 10a, 1.16.26). Regular app icons stay in place, but the direct link to 'My Apps' of the Playstore keeps disappearing after a couple of days after re-adding), but also the shortcut of a Progressive Web App (PWA) keeps disappearing.

Not a huge issue, but never had it before (though have this new phone for 2 weeks now).

Regards Chris
