"Convert records" actions are getting extremely slow

Please take a look at “convert records” actions.

I have been using these for more than a year. The action is basically take some fields from actual sheet and make a new record on another sheet using these fields. On “advanced” features I have only checked “recalculate all the formulas on the target sheet”

It normally takes about 5 secs when I hit the action button and the message “Action x execution complete”.

Since last week, it is taking more than 30 secs for a single convert records action.

Somehow it is fast again!
Will update if the slowdown happens again.
