You get one transfer in or out of your membership per UY. The only way to get some in and out is to have them be from a different UY, as in calendar year, not different UY as in the month.
For example if you transfer out Aug 2023 UY points, that counts for your 2023 UY transfer. You would not be able to get any 2023 UY points, even if they were a different month.
But, if you transfer out 2023 UY points, you could then receive some 2024 UY points, no matter the month.
