I just wanted to add that I have now been able to, in Ancestry’s terminology, upgrade my cancelled account … it’s now back to being a Full Access account, just as it has been for years. I still can’t update payment card information on my profile but I have been able to set up payments using PayPal. The person I spoke to earlier told me that this was not an option when I suggested to her that it might be a solution and instead cancelled my account because she couldn’t fix the card payments glitch. Ironically the cancellation was what brought up the PayPal option. That said, beware the Ancestry telephone helpline!
I really would be interested to know if anyone else has had similar issues … I’m struggling to believe just one account would be affected by this, it feels like a software glitch at Ancestry’s end to me.
