I have a pdf form which contains a date field in the format 'dd', i.e. from 1 to 31. When filling with acrobat reader it works fine and i can insert any day number from 1 to 31. When filling in edge, it will automatically change the dates 29, 30 and 31 into respectively 1,2,3. I believe edge pdf reader assumes that, as currently it's February, there cannot be any date greater than 28... See videos https://imgur.com/a/tPyNc7F
