Not upfront about ££ to access content
£3 to set up an account and further £9.99 to access colour photos! Had I have known this in advance I would not have selected this app! From your response I guess other people have ended up with the same unwanted subscription, it looks/feels like it’s part of your app to trick people to sign up. The 3rd party may not be your responsibility but sorry to say I believe your customers and how they are treated whilst accessing your app are your responsibility. Presumably you have a choice to disassociate yourself with these advertisements.
