Hello,
1. You can cancel your recurring payment via paypal at any time, and at the next billing session your subscription will go back to free.
2. I haven’t tested pruned nodes but they should work, at least in theory. I don’t see why not. If they don’t, please let me know.
3. Generally the plugin does not communicate with MyCred.
However, you can use the PHP API to override any user balance. Please see: https://wallets-phpdoc.dashed-slug.net/classes/Dashed_Slug_Wallets_PHP_API.html#method_api_balance_filter You will need some knowledge of PHP to do this. Hook into the filter with a priority higher than 10 and override the balance value with whatever value MyCred gives you for the requested user…
with regards
