Windows 10: Roblox gets really laggy when i play it on Microsoft Store App

When i join Roblox experiences, Roblox gets really laggy, this didn't happened to me before.I wonder if it's just my internet, since when I go to houses where there is fast internet, my experience is good but in other places, it is not.Is there a way to fix this and get my gameplay back to normal and fast?

Roblox from Microsoft Store play button not working

When I tried to play a game in Roblox downloaded from the Microsoft Store, the play button wouldn't work. When I clicked play, the Roblox page just stays frozen.

Are there any fixes to this? I tried reinstalling the app and restarting my computer, but none of that worked.
