We are having the identical problem and I can confirm:
- We have RC v 3.2.10 installed.
- We have tested with other themes including the Twenty Twenty theme.
- We have tested deactivating all plugins except RCP to test for conflicts.
- We have examined for JavaScript console errors and there are none.
- We have set up the webhooks as per the RCP documentation.
Like @doulos12’s video shows, we get through the Stripe connection authorisation popup, it appears to connect, but then loses all its settings immediately.
