Currently I am using the Starter package and want to try the "Video Sharing" feature.
Can I have a trial first for several days before upgrading to Pro?
I have also read that if we wanto downgrade, we have to contact the customer support. How? Thank you!
Yes, your trial should last at least two weeks with GoToWebinar before you have to purchase to continue.
If you need to downgrade, you may disable the current subscription renewal, and then re-subscribe after expiration to a lower tier.
