Integromat iOS app not refreshing via background app refresh

I have the Integromat app installed and Background App Refresh is set to on in iPhone Settings. In the Integromat app I have it set to refresh as soon as possible. The problem is, it doesn’t refresh. I have to open the Integromat app and then it will sync. Any thoughts on how to fix this?

Just tested by adding an iOS notification to the scenario. The notification comes through immediately but the contact doesn’t sync until I open the Integromat app.
