iPhone 7s, iOS 10.3.3, Spotify 8.4.8

Steps to reproduce:

1. Play music from iPhone. (Just happened using the built-in speaker; not sure if this matters).

2. Receive a phone call. Music pauses during this time.

3. Answer phone call.

Expected result: music stays paused.

Actual result: music resumes playing while on the phone call.

This only started within the last couple weeks, but not sure the exact Spotify version that caused this. Super annoying, as my job involves handling lots of phone calls, and it's quite frustrating to start every call with "one moment, my music keeps playing over your voice - gotta go to Spotify and pause it".

Not sure if this helps, but there is a lengthy thread about this same issue happening on Android a couple years ago.
