The way I wish I could use free trials is with a free trial to paid instant course unlock.
I know you could do a 7 day time unlock but if there was a free trial to paid unlock, it could push members to upgrade to paid sooner than 7 days with instant unlock.
After considering how to implement this in my group, it’s the 1 big thing I would use to implement trials that I don't have.
Similar to the function of time unlock compels members to want the annual upgrade.
Trial unlock compels the upgrade to paid sooner.
