Input lag makes game un playable

I have been playing D3 for a long time and on multiple different platforms. I’ve been playing on a pretty beefy laptop and have never had any issues. recently I have been having game breaking input lag that makes it un-playable. this input lag has come out of nowhere; I haven’t changed any settings or done anything different. I was playing the game with some friends and once they got off and I joined a public game that’s when the input lag happened. my internet connection to all the instances is fine but the delay from me pressing the skill and it actually preforming the skill is delayed about a second or two now. nothing I do or try has fixed this. please help.

Yep I’m having the same issue with the crazy lag. Also I’ve crashed 5 times tonight in the space of 3 hours. I’m have a new computer, and don’t see any other issues with my internet.

This has been the most bugged season ever.
