I am using adyen sdk 3.13.0 to render custom card component. My issue is I couldn't navigate to next inputfield from credit card input field by single tab key press. I need to press tab key 3 times to navigate from credit card field. But this issue is not present in any other fields like expiry or cvv. I could see two extra input fields in creditcard number iframe. This won't be present in older vesion of sdk.
I have checked the same in version 3.3.0 and it is working perfectly fine
The two extra input fields that you describe have been added in order to help with credit card auto-completion. They get a tabIndex of -1 so as not interfere with the tabbing process.
Sadly, in one scenario, Chrome on iOS, we cannot set this tabIndex attribute because otherwise the auto-completion will not happen (!?) However it would seem that this (no tabIndex attribute) is now also happening in your use-case (Chrome on Ubuntu).
We will look further into this - and try to find some way to reproduce the issue (we don't work on Linux machines). I suggest you contact Adyen support in order to make a ticket for this issue and get it registered in our system
