Please help I think I'm going mad. I only use IPhone iPad and iMac. My son (11) insisted he wanted a Samsung tablet. Saved up his pocket money and got it today. I set it up for him on his google account which is linked to my google account as parent. So far so good. Now he wants to buy an app. Fine except his tablet says get your parent to add a payment method on Google Play family library. I have tried to do this but it keeps telling me I need to open the google play app, except I can't because I only have an iPhone! I can't find a way round it. I've tried adding my account to his new tablet but it won't let me do that either. Is there any way round this?
