QuickBooks Online

Like others, I am getting the following message: Something went wrong.
Failed to provision account. Error=AccountInactive: Your account has already been successfully migrated, or migration is in progress, so this connection can no longer be modified.

I have contacted support via email, received a response, replied to that response and have not received a response from them 4 days later.

I used the QuickBooks online chat facility to try to resolve the issue, but the support staff is not even aware of the Shopify Connector app that we are have foreably migrated to.

Really dissapointing.
