Update 2.1.7 no longer able to edit Apps and Drivers code

Anyone else with this issue after updating my hubs to the latest Version 2.1.7. I can't load the old user apps or drivers for editing. This is happening to both of my hubs. Reboot did not solve the issue.

I have it on a computer with Firefox. Chrome works fine.

Loading for me OK using chrome on a PC.

Thanks guys. Guess just me on this one. Will investigate further.
