I asked Novo if they're planning on continuing to be compatible with QBO. This was their reply,

"Yes, Novo will still be compatible with QuickBooks. At this time, we have not been provided a timeline as to when this will be resolved, as our Technical Team is currently working with QuickBooks to have this resolved as quickly as possible. Once the QuickBooks connectivity error has been resolved, a notification will be sent out to all the account holders that were affected by it, as well as yourself. Again, I truly appreciate your patience with this, and I do apologize for the delay as well as the inconvenience this may have caused."
