I succeed pwa(twa) app deploy google play store. but i faced the problem that pwa splash screen icon is too big when download application on google play store then launched app. How handle this? i used pwabuilder tool(MS Tool) that convert apk. i think manifest is no problem. because add to home is works fine. splash screen is works. But only problem is pwa app downloaded from google play store. any advice welcome.
