I have a very important sheet that updates via a banking API and is pretty crucial to our workflow. Yesterday morning, all the scripts stopped running. All I get is the Execution Started notice and the spinner. No code is executed although it does show as launched in the logs.
I even tried to recreate with the simplest possible Hello World script and that too hangs until it times out.. We're nowhere near use limits, duplicating the sheet has the same problem, and it happens across multiple user accounts. Creating another sheet and moving Hello World works, although I haven't tried any of the more complex scripts.
Anyone seen this before?
