Music keeps pausing / skipping since updating to iOS11

Ever since I updated to iOS11 (specifically, I'm on 11.0.3 right now) on my iPhone7, my use of Spotify has been completely messed up. The music will just randomly pause or skip to some random place in the song. Sometimes it works fine, and sometimes it will do this so frequently that it's unusable. There seems to be some correlation with movement. For example, it happens a lot when I first stick my phone in my pocket. Sometimes instead of just pausing it will cause Apple Music to start playing. (When this especially annoying feature kicks in, I can usually get rid of it by rebooting.) Often, none of my earbud controls will work, or if they do, the pause button will cause Apple Music to start playing. This is almost certainly an iOS11 issue rather than a Spotify issue because not only did the problem start exactly when I updated, but I noticed that the problem affects apps other than Spotify (though Spotify is the app I used the most by far). Please fix this, because I'm at my wits end. I'm highly tempted to just nuke the phone completely and start fresh.
