Notes app says wrong password, but passsword is correct
I'm trying to lock a new note but either macbook and iphone Notes apps are saying Notes password is wrong, when I enter this pass in old locked notes, I can unlock them, and yesterday was the last day I locked a note (with the same password and I can unlock it, but no new notes since today)
I dont have two step verification process, and didn't do any changes in settings in icloud.
I dont know what to do
also Face ID worked yesterday but today dont, and entering manually the pass works!
In iOS settings/note/password, I'm trying to change it but says this password is not correct, how can be this when I can use it for the notes locked before today???
I use a special formula for passwords, is impossible to forget one, and if I accidentally change one, this would be the same as before! as I do always same maths
thanks
