Hi ,
I already subscribe to yearly plan but currently i change my mind want to subscribe for monthly only.
Is it possible to change it ?
Wait until your time is up, then support to monthly. To change a gdevelop plan you have to cancel your current play (Which terminates your current agreement) and you will be billed immediately when you start your new subscription.
Set a reminder to cancel your yearly right before renewal. Gdevelop does NOT pro-rate account sub changes.
