I was poking around the Amazon OS settings app, and noticed that they included option buttons to wipe the cache and stored data of individual apps.
It was so bad last night that it could no longer switch between stations or even go back from viewing a graph. I assumed that Amazon’s software bloat over the years was making the WF app run increasingly slower as time passed.
Interesting discovery about my ancient 5th gen 7' Fire tablet that has been running the WF Android app betas 24/7 since the early field test days.
