Is there any cashback card that do NOT refund in RM XX blocks?

Sample taken from Citibank TnC:
If the accumulated cash rebate is less than RM20 for a particular Billing Month, the total cash rebate amount will be carried forward to the following Billing Month, and will be taken into account in determining the Cardmember’s cash rebate entitlement for that following Billing Month. If the Cardmember has not accumulated an aggregate of RM20 in cash rebates for that Billing Month, the
total accumulate cash rebate amount will continue to be carried forward to the subsequent Billing Month and so forth.

By refund, I mean credit cashback amount.
Citibank pays in RM 20 "blocks" so if it takes me 4 months to accumulate RM 20 cashback, I'll only get RM 20 after 4 months. It used to credit in RM 50 blocks so RM 20 is better now but still takes a while to accumulate.

Was wondering whether is this common practice or is there other bank that credits cashback for any amount within statement month e.g. RM 0.50 cashback.

Did a quick scan through on Maybank's FC Barcelona Cashback card TnC and Product Disclosure - looks like Maybank doesn't have this rule. Can anyone with experience pls confirm? Thanks.
