We can confirm that we have resolved the issue with our Making Tax Digital application. A fix has been implemented and we are monitoring the results.
In order to be able to submit your return you will need to do the following:
1. Deauthorize the HMRC App from within Brightpearl.
2. Reauthorize the HMRC App.
(Please see the link below for detailed instructions.)
Then make sure you have not marked your current return as reconciled.
Then go to the VAT return page, click "get obligations", and submit as normal.
Please see the following guide for full instructions on the above: https://help.brightpearl.com/hc/en-us/articles/360025319851-HMRC-integration-for-Making-Tax-Digital-MTD
Thank you all for your patience.
