[BUG] Dual SIM iPhone takes long time to connect to Spotify server

[tomasvaril]

Issue Description:

I have been having this issue since I bought my dual sim iPhone Xs Max and started using both SIM cards. When I resumed or started the Spotify app it took about 20 seconds, in some cases, to connect to Spotify servers, which was really annoying. I tried log out and log in, I deleted the app, nothing helped. Finally I discovered the issue is connected with dual SIM setup with both SIMs activated and using mobile data (no WiFi). Cellular Data Switching toggle does not have any effect on that. If you remove or disable one of the SIMs the issue disappears.

Device

iPhone XS Max 256 GB

Operating System

iOS 13.5.1
