I am having the same problem with my Mi 10 Note with Vodafone Germany and I am close to throw this unusable phone out of the window. Even with Xiaomi.eu-ROMS the bug did not vanish
I am totally disappointed and cannot find help so far. Originally it worked fine, but all of sudden no chance. I switched to a Xiaomi.eu-ROM but the mistake stays.
For a business phone a real nightmare!
