Ever since they updated the look and feel of their website https://www.malaysiaairlines.com/th/en/ I cannot seem to book BKK-MNL or MNL-BKK, obviously via KUL.

When I enter BKK as the departure city, it resolves correctly to Bangkok. But then MNL is not present in the destination city box.

However, If I enter the destination first, MNL is resolved correctly but erased once I enter the departure city as BKK.

Same is true for the reverse.

Google Flights still shows these flights no probs but if I try to book it via the Google Flights link it takes me to the MH website with an error message.

OTAs can book these flights just fine but I need to book directly for the Amex 5 x mileage bonus :P

Have reported to MAS twice but never heard back other than an automated acknowledgement. Can anyone else replicate this issue ?

I tried 3 browsers, incognito mode, VPN - all of it to no avail.
