Supermetrics Functions General Error

 Hi

I'm doing some tests to see if supermetrics functions is suitable to us.. and on those tests sometimes on a query I have a general error

Sometimes it did work, but it's rather erratic.

I thought it could be about too many results, so I added a 50 maximum, but even with that had issues.

I was thinking of purchasing soon, but in this case if it doesn't work everytime, will have to think on the case.

Thank you
