Blu Android phones can be had very cheaply on Ebay ($25-30 delivered). I have one - the Fordpass app works fine on it.
iOS 18 beta 4 + FP 5.3.0 still giving me the page load issue as well.
Thanks so much for posting. I have this issue, glad to know I won't be wasting my time. I will copy this so that the service can hustle getting it done.
