Cant see cards on file or charge card on file qith andriod user

[Ceira]

It Will show me in customer directory what clients have cards on file, but it doesn't show the last 4 digits of the card on file. And when I make an invoice for that client I am unable to charge the card file as it does not give me an option for that. It's only doing it on our android users, not iphone users. I reached out to tech support. They were unable help. Is there something im missing?
