Hi @anton2oc,
Without a product area to test, we can only test on our own sites with devices, and we are not seeing any errors with Apple or Google Pay. In this case, double check with the settings for both based on the setup documentation at this link.
It is also possible if everything is set up correctly, that there is a theme or plugin conflict which is causing the buttons not to operate correctly. To test this, make sure to have a staging or test site – a staging site is a clone or copy of the Live site, used for testing. You can reach out to your Host if you need to have a staging site set up, as they usually can assist you with this.
With the test/staging site, do the following:
1. Temporarily switch your theme to the Storefront or Twenty Twenty Theme.
2. Disable all plugins except for WooCommerce and Stripe.
3. Test to see if the issue has been resolved.
If that resolves the issue, then one-by-one you can switch back your theme and re-enable your plugins, testing in between, until you find the one causing the conflict.
Let us know the results!
