When making a connection from Zed Axis to QuickBooks Online, the popup window appears with the message.
"Unsupported Browser, We have detected that you are using an unsupported web browser.".
This error started to occur on May 27th - we believe that it is related to an update made by Intuit to the QuickBooks login pages - we have raised a ticket with Intuit and are in the process of trying to determine with them the cause so that it can be resolved as a matter of urgency.
There is no workaround this issue at the moment and I apologize for the inconvenience caused. It is our highest priority to get this resolve but at this point we believe the issue is on the Intuit side and we are reliant on them resolving it. Any updates to the issue I will post to this thread and when the issue is resolved will tweet that, @ZedSystems
