Thanks Mohammad. I am able to re-produce the issue. 

What is happening here is - Chrome is using "frecency" algorithm to re-order cards when selection is done. So after selecting card, even discarding it is resulting in frecency algorithm that is keeping card before "Gpay" logo suggestion. We can play with this well if we have two cards as suggestions.

I checked how this is handled in Desktop GPay branding to see if "Autofill settings" has any special sorting built in. In case of Autofill, frecency is not happening that frequent. 

Let me bring that up in team meeting tomorrow. Once I understand that, I guess fix should be relatively easy. 

Thanks for spotting this.

Do we not always add the GPay logo as the first option regardless of the sorting of the autofill suggestions?

We add it as first option when sending suggestions and thats why we see "GPay" is getting animated. After that it is getting sorted on frecency. What is interesting here is this seems to be specific iOS behavior as we don't see that re-ordering same page happens in other systems (Linux). 

Let me discuss in the team meeting.

Discussed in the team meeting and logged (https://bugs.chromium.org/p/chromium/issues/detail?id=852529). 

Assigning to Mohamad since he is doing the eng work on (https://bugs.chromium.org/p/chromium/issues/detail?id=852529) that should fix the issue here also.
