Buffering after Firestick update

I posted about accidently bringing my firestick back to factory settings. I had to re-install everything including what was my perfectly working Smarters. The firestick did update through Amazon. I have done everything that I have come across to do on this site except new equipment. One thing that is in the back of my mind is did I add different players to the previous one OR has something happened when the firestick updated on amazon. I do have a vpn. I have tried both on and off. We have 4 paid subscriptions here and it seems after the update recently, they are all buffering. My Mbps are all good. Thanks in advance for any advice…

When encountering buffering please take a look here, lots of info.

Force stop and clear the cache on all your apps that includes all your players too.
