Does anyone knows how to solve the issue with regards to unable to link Maybank?

Hello there, jinxian0701.

Upon checking on my end, we have an ongoing investigation of being unable to link Maybank to QuickBooks Online (QBO) (INV-98230). With this, I recommend contacting our support. They can add you to the affected user's list, and you'll be notified via email once the update is available.

Here's how:

1. Log in to your QBO account.
2. Click Help (?).
3. Select Contact Us and choose a way to connect with us:

• Start a chat with a support expert.
• Get a call back from the next available expert.

Please also note the supporting hours for QuickBooks Simple Start, Plus, and Essentials. They are open from 6 AM to 6 PM, Mondays to Fridays, and from 6 AM to 3 PM on Saturdays. QuickBooks Online Advanced support is available anytime and any day of the week.

In the meantime, I suggest manually uploading your bank transactions to QBO.

Please keep in touch if you have further assistance regarding creating estimates in QuickBooks Online. I'm always here to lend a hand.
