Shameless plug: my app Homechart (https://web.homechart.app) doesn't really have those issues (uses Mithril and extremely limited dependencies).
I then scrolled again and this time it worked. I then refreshed the page to try again but noticed that the page started already scrolled and I couldn’t get it to properly centered right.
After yet another refresh I was getting the original scrolling issue. I also noticed that when scrolling down the top portion of the screen is a solid white bar which looks out of place.
I say all this not to pick on you but I constantly see web devs talk about how great you can make a PWA but it is constantly all of these little oddities that make the experience feel so subpar compared to a native app.
