@JessT  Unfortunately your response has ignored again what we have been saying. We have had our settings within Quickbooks checked, double and triple checked but the issue is with Quickbooks software.

Regardless of how many times we untick and recheck options within Quickbooks and browser (tried on different browsers and platforms) settings, the problem persists. We do not have the time to waste repeating these steps at the request of yet another support staff. It's akin to banging your head on the wall and expecting it not to hurt after trying it again for the 100th time. 

Please escalate the matter further up the chain of support so that the issue maybe fixed.
