Need help.

MDx

I'm facing a lot of missed inputs , particularly on dashing back . Be it in quests or battlegrounds , but seems more in battlegrounds. It's a 2 yr old device that was flagship then so it shouldn't be a problem , tried after reinstalling and clearing cache too. Been having this since a few days , ignored it at first as my fault but now it's more than ever, even occuring in every match in bg.
Anyone else facing this ? Or its just me ?
