AirPlay HomePods doesn't work properly on iOS 13.4

Device

(iPhone 8, iPad pro 10.5, HomePod)

Operating System

(iOS 13.4)

After updating Spotify (v 8.5.50) and iOS (13.4) I started to have a big problem with connection and sound of my stereo paired HomePods (OS 13.4). They are not playing as a stereo and the sound is out of sync. Also, the sound often falls out, but the song in Spotify app still playing. Tested on iPhone and iPad.

In other applications everything works fine.

I restarted my iOS devices and both HomePods but it doesn't help.

Does anyone have the same problem?
