Seems like you dropped an update today, since I had to give Postman access to my firewall again.
I am now unable to directly open any test folder or test from any of my existing collections. When I click the test or the folder, the panel on the right hand side goes blank. I can right-click - Open in Tab to open a test, but I CANNOT OPEN A FOLDER.
The folders in our test collections contain the global pre-request scripts for the test collection and we are now unable to maintain them.
Iβm using the desktop app. Clearing the Cache and reloading did not solve the problem. Clicking any folder or collection in the workspace does not open the folder or collection. Folders are complete inaccessible now.
