While I doubt remote working contributes to the shitty app, the following specific things annoy me:

* Opening the app on my phone while music is playing on my desktop causes it to start playing on my phone automatically at max volume.

* Closing the lid of my laptop when music is playing on my phone causes my phone to pause the music. (Here's a tip: I'm closing my laptop because I'm leaving, therefore I want to use my phone.)

* Having a weak internet connection causes the album page to take forever to load. (This is for albums that I've downloaded.)

* Gaining/loosing internet connection while scrolling causes the scroll view to jump to the top.

* Every time I reopen it I have to click on the album view.
