Hi there! The 2.0 Customer Portal supports mobile usage and is compatible with Apple devices across various models, including tablets. Usually, when customers have a challenge with the payment functionality, it’s because of a device issue, an ad blocker (ad blockers love to mess with the payment feature!), or an internet/connection error. I would recommend having the customer restart their phone and try again. You can also suggest they try clearing cookies/cache.
Note that if you’re using the 1.0 version of the portal, mobile devices are not supported, which could be causing the issue here. It’s one of the reasons we recommend upgrading to the 2.0 portal! 🙂
I found a work around for that in the 1.0 portal. If the customer enters that information in the same layout (routing/account) in the notes on their phone they can copy and paste it into that field on their mobile device.
