Vizio app Running slow

Vizio app Has been running slow and very laggy since last big update a few weeks ago. It was working just fine but after update to server it works like crap. It takes a few sec to switch to a different movie or tv show for it to move. Outside of the plex app the tv works fine with any other app ect. Before I am asked this is a brand new 50 i just got and the start of August of this year. I am just wondering if anyone is having the same problem or is it just me. If you are have you found a fix and if so can you help. PLease and thank you
