So I have the Firestick 4k max. Got the latest update about a month ago. Currently on fire os 8.1.6.9 using about 5gb of storage. I have been watching videos. Cleared all the cache. Unplugged it. Restarted it. Tried other "fixes" but it still lags. I'm wondering if there's anything that will actually fix this or if resetting to factory settings will even help. I honestly don't even want to do that but wondering if that will fix anything or if it'll be a headache for nothing and a waste of time? Any helpful suggestions are appreciated.
