Same here, 2014 AP1 version, browser worked slow but good for several years and Then started to halt, freeze.
I used it often to check mail (yes, webmail worked just fijne in 2016, look up opening hours and have family photo's on big screen.
Now it goes wacko after a day.
The most anoying thing is that,as a user, there is no way to reset the damn thing once it freezes.
Even a hard reset of the system keeps the browser in a dead lock.
Since Elon is a fan of retro, i could love you have a good old fashion reset button on the browser screen... Or an escape button, (Apple style?!?)
And honestly, fun gimmicks like fart sounds are not welcome when the same release contains broken features
