Hi Kamil, thanks for sharing your experience.

The phones aren't MDM managed; I experienced the certificate removal 
issue on Motorola Defy and CAT S62PRO (both Android 11). Maybe that's 
something wrong with my self signed CA and client certificates... May I 
ask you how did you generate your certificates?
