Since around 24 hours ago I had the issue that the custom functions in Google Sheets are not able to be executed - it just does not run the function at all. If I look at the app script executions, it does not even show up the function. It happens very randomly. It stopped running for 12 hours since 13:30 yesterday (GMT+8). It worked this morning up until now. And now 30% of my sheets could not run custom functions.
It could not run a function as simple as this: function double(input) { return input * 2; }. It keeps showing "loading".
If I enter the GAS console and run manually it's totally fine.
I wonder what's going on and it's extremely annoying.
