M2 Visa/MC/Amex doesn't require the transactions to be online for CB/rewards.
For M2 Amex, you can get 5% weekend CB for bill payment at M2U EXCEPT Government bodies, utilities and via Jompay/FPX. Only very few bills you can pay using Amex at M2U (not via Jompay).

Almost all the banks will not give CB/rewards for Jompay/FPX transactions.
