Huawei Syncing Issues + no vouchers from Multiply

Having syncing issues with Multiply's app. Our Huawei Band 9 syncs 100% to the Huawei Health app, but doesn't pull through to the Multiply App.

We are missing 3 weeks worth of vouchers (+1 monthly win) that goes to our Health Saver / Savings account for our daily needs.

Multiply's chat just says that there are issues with Huawei at the moment and no further comment about it... I had to save screenshots as the chat transcript can't be sent to one's email address anymore.

Please advise when this will be sorted out.
