Thanks, Polina! Let me know if there's any further info you need from my side:
Here are more details on the device:
Android Version: 11
Android security update: September 5, 2020
Google Play system update: September 1, 2020
Baseband version: g7150-00018-200701-B-6643937
Kernel version: 4.14.170-g501c771385ff-ab6716795 #1 Tue Jul 28 22:05:21 UTC 2020

As I mentioned, this is a Google Pixel 4a. The phone is less than a month old. Admittedly, I did not try the RU app prior to allowing the phone to update from Android 10 so I cannot say if it's something specific to the hardware or the Android version.
Happy to perform any experiments that you would like!
