If your Graceful.Dev subscription info says “RubyTapas Legacy Membership”, that’s because you’re a member on RubyTapas.com, which automatically confers Pro membership to Graceful.Dev!
For Legacy RubyTapas accounts, you’ll continue to manage your billing (including pausing, cancelling, or updating your payment details) on that site. Log in to RubyTapas.com, and then go to Account -> My Subscriptions.
For the ease of all involved, Legacy RubyTapas account management will remain available indefinitely, even as the RubyTapas content moves to Graceful.Dev. If you would like to make a clean break and move your billing to the Graceful.Dev site, please get in touch!
