Our developers are aware of the Invalid subscription customer_id
issue. It seems that due to account-related changes in WooCommerce version 4.6.2, that the Subscription error appeared on sites where the Checkout was changed from default (i.e. using WooCommerce One Page Checkout, Elementor, or other plugins). They are currently looking into exactly what causes the issue, and the best way to handle/prevent that error from occurring.
Please keep an eye out for new versions of the extension, and you can check the changelog for updates here:

In the meantime, one workaround is to go under WooCommerce ? Settings ? Accounts & Privacy and disable both of these settings:
– Allow customers to place orders without an account
– Allow customers to log into an existing account during checkout
Let us know if that works. ?? Thanks!
