[Stripe] In our ecommerce in last days we have this wrong behaviour, some user pay correctly with order on processing state

Hello Dmitry and thank you for your support. I am trying to support my teammates to resolve this issue and now payments are fine but order status is still pending. We have upgraded Stripe extension to latest version. Only in case of 3d secure.

I will not support you and your teammates for free anymore.
If you need my expertise after your server moving / changing / etc, then you should buy my Magento 2 monthly support service.
And I will need SSH access to your server.
