Hello,
The Stripe Connect plugin (and HikaShop recurring system) is not compatible with Stripe recurring system.
Regarding your feature request for the creation of "customers" during the checkout, it would require an important development which will affect a big part of the workflow.
It is not possible to create a new customer for each transaction, because it needs to check that if a customer already exist for the HikaShop user ; if it exist the plugin needs to update it with the new details (address, etc).
The Stripe Payment Intent API allows to give the customer address and classical details to the platform.
Since HikaShop is handling your customer database, there is no common need of deduplication and transfer of all client data to a SaaS system.
