It’s still unfathomably slow, and now seemingly even more unstable. The Android App is night and day more performant and remains rock solid.
Context: The previous Widows App update was a car crash. Slow, laggy, and locked up frequently. Other users (not me, thankfully) even reported being unable to see content in it. This morning (my timezone) there was an update. I was hoping it would fix things. It only made it worse for me.
Temporary workaround if you have a mobile device, and what I’m now doing:
Run the Android (guessing this works for apple, too) App through Windows Phone Link. You lose a lot of function, obviously, but at least the core element works this way.
