I've got the exact same issue. Tried multiple browsers, tried clearing cache for the browsers themselves, tried deleting history and everything else on the browsers themselves, tried shutting down and clearing the cache from the phone itself. Nothing seems to work. Every once in a while it'll start working again for about 2 minutes and then once again ceases to work after that.

I have the same issue on s21plus. Switching to Firefox helps, so maybe it is something related to WebView component or WebKit (I suppose majority of people has tried and faced the problem in browsers based on WebKit which Firefox does not use). Still pain , I don't want to use Firefox...
