'simple' mode doesn't unmute at the end of ads

[Kabur]

Using spotify version 1.1.5.153.gf614956d on ubuntu 18.04.02 LTS. Continuous mode works as intended though. On 'simple', when the ad gets played, spotify mutes, but it looks like the ad gets skipped because I just see my song's progress bar - I can move it, skip to next song, or just wait, but it never unmutes until I restart(and sometimes even persists through restarts).
