We have released a maintenance version to 4.4.2.
This is a result of Xero forcing updates to API V2 for all clients. Note that as of this version you will need to update your connection to this API to continue using the Xero integration. If you require assistance with this process please feel free to book a support session. The server for the cloud clients will be offline for approximately one hour at 8 PM AEST.
We thank you for your understanding.
