I have used firesticks or a cube for years. And I’ve worked out all the issues that pop up. But usually, it’ll be one device. Not all three. But both kodi and youtube (the videos play fine once loaded) are now taking insane time to upload. Its A PROBLEM I have never seen,.
Yes I did master reloads, reinstalled apps, my internet is blinding fast.
I have noticed same thing on my firestick, didnt matter if vpn was on or off, weird thing it was always in the evening, when i tried it in morning it worked, i also notice on one of my addons i was not getting any streams, however the same addon on my nvidea shield got many streams. I only had two apps on my firestick, kodi and youtube. So there was plenty space and memory. Tried cleaning everything, still same problem. To me seems like amazon may be responsible. I got fed up with this and replaced my firestick max with another nvidea shield. Now i am happy again.
