If you need more help that you can get here, I can provide it, as it’s how I make my living. https://www.literatecomputing.com/. You can contact me directly or post in #marketplace. I’m trying to be on vacation now, so I’m not as responsive as I usually am.
Err. Since “membership” and “subscription” are near synonyms, I can’t quite recall. I vaguely remember trying to get subscriptions to work and switched to Memberships (the client had both). I’ll be available in a week or two, or sooner if it’s an emergency.
