I just did an update on my Max. First off I turned Wolf launcher off and returned to stock to do any updating. It didn’t update the OS from 7.2.5.5 to 7.2.7.5. It did add a new option for auto app login. It was set to on by default. It was under the developer options section. I turned it off. After turning it off and going back to Wolf I could not find the option, so I went back to stock and the option was now gone. No idea how or why. For now I’m back on Wolf without any issue. When the FireTV OS does update I’ll report my findings.
Have fun and STREAM ON.
Another observation. This nothing update took me from 2.36GB of free space to 1.97GB
They will seduce you into their web by offering you some shinny new gimmick to entice you. Then once you take the bait and do the update, You are stuck!
