I originally tried to use only the trial version. So I want to cancel my adove plan and searched how to cancel on adove site. but I can not find cancel button. and I tried a lot to change my payment information. but it didn't change,,,,I don't know why,,, whenever i tried to change, there is a problem with updaiting the payment information. I already tried to all my card...and is it possible to cancel the plan only after monthly payment has been made?
