Hi Chris and humorkritik, thanks for the tips. I think I had already done the things you described, but I tried them again just to be sure, and also because I finally managed to upgrade to the current OS since my last message (it took a few tries) - I wondered if that might also make a difference. Sadly, it hasn’t, and neither has following the steps you suggested. Chris, I’m as sure as I can be that I chose Pay as you Go when I used the Co-op form, as that is the plan I’m on - but this is based more on assumption than having any actual clear memory of doing so!
I think I might need to phone the Co-op…
