When you buy something in a foreign currency, Monzo estimates the GBP equivalent.
It uses that estimate for calculating the pennies to move to the coin jar.
Then, a day later, the actual exchange rate comes through, which (unless the estimate was spot on) throws off the total.
I bought something on Saturday for $35.00
Monzo estimated an exchange rate, 1.265, and a GBP equivalent of £27.67
It rounds it up to £28.00 and puts £0.33 into the coin jar.
Today the actual exchange rate comes through. 1.25. GBP equiv of £27.92
The nicely rounded up £28 is now £28.25
Nooooo… now it looks untidy. Extremely low priority, but still.
What I’d expect is that it’d take a few pennies back out of the coin jar (or put a few more in) once the final amount comes through.

Enable saving pennies to another pot
Buy something using a non-GBP currency.
Wait a day, re-examine the amounts.
