I am also having this problem and have spent over an hour trying to sort it with one of your chat team.
I use a Mac and have tried the following; logged in with Safari, Chrome, on a different network, using a private window and cleared my cache. I am still getting the empty screen at the end of each session.
I use quickbooks to do the accounts for 4 companies and will need to look at other options if this issue can't be resolved.
