Easy Access interest not calculating accurately across timezones

I’ve got £5k in the account, yet it says I’ve earned £13 today. That should say since the 1st of May not June.

Details to reproduce:

Go to Japan at the end of the month. I guess changing your time zone will work too. However, I think Monzo should pay for a developer to fly to Japan just to be sure.

OS: Android 12 (I think)

Device: Fairphone 4

App Version: Latest



Could it be that the interest is calculated using the date and time in UK where the bank is based?
