I use Giffgaff as my mobile provider. Before SailfishOS 184.108.40.206/11, I was able to top up my phone using Giffgaff's website.
Now when i get to the confirmation page, there is a big yellow rectangle saying CONFIRM, tap to proceed, so I tap it, but the page just goes round and round in circles, always back to the big yellow confirm button, but never actually confirming my purchase - leaving me unable to top up.
I have also tried the Giffgaff Android app, but it sees my device as rooted, so I cannot use that either. The last time this happened, I was handed an HTC M8 that had seen better days, but within minutes, I was topped up and ready to go, so no problem with Giffgaff's website.
