The Ring Intercom Unlock (and possibly Talk) notification is using MM/DD/YY date format when the Android 10 phone is set to DD/MM/YYYY date format (eg. UK region).
Obviously the date on the notification should be 30/10/2022.
In addition, the time format on this phone is set to 24 hour, so the use of 12 hour formatting for the time is incorrect too.
Presumably the US preference for date and time formats has been hard-coded into the Notification system, which is pretty much unacceptable in a professional product with a global target audience.
In Techie parlance: Ring, please localise your notification dates and times.
