I've just installed and run the DRM Info app. To my surprise it says that the Samsung A55 only has Widevine L3. This phone supposedly have Widevine L1. Do you also see L3 on your A55? Does anybody know what's happening?
Note: this is important as with L3 Netflix will play content in 480p only, while with L1 it will play content in 1080p and HDR. Big difference, latter is a lot sharper, had better contrast etc.
Solution found: 1) Install DRM info app and check security level. 2) If security level is 3 then restart the phone and check again. 3) Now it's level 1 - for a few days... Keep restarting the phone to keep it at level 1...
