Android 11 tablet.Hmm so you say that is for all browsers for you? What platform are you on btw? Any adblockers or extensions / anything running on the side of your computer that might be doing anything with javascript?
For me I have no slowdowns, even on mobile devices. But I only have mac set up at the moment, can dust off my PC for testing if that's what's causing it for you.
Anything else about your setup of note? Whats your hardware specs?
I only ran the latest version in Google Chrome. Previously, I tested it on Google Chrome, Microsoft Edge, Brave, Yandex Browser, and Firefox.
Default browser settings, no ad blockers or other modules.
