Houzez recurring payment issue UK - It doesn't work

Can ANYONE confirm whether they have successfully used the recurring membership stripe payment in Houzez? I have an issue where only the first payment is successful. All future payments are not recieved in Houzez although successfully processed in Stripe. Any Webhook test from Stripe to my site is successful.

Houzez author is using a legacy version of the Stripe API and refusing to update as it requires a rewrite.

During payment the following error is visible in the web console:

You’re using the legacy version of Stripe Checkout.

We released a new version of Checkout in April 2019, which supports mobile wallets and other payment methods:
