Apparent Bugs?

To preface, I recently turned 18, so that might be screwing up some of the interfaces.

So basically, I cannot interact with the gift tab on my mobile device (on the pc client is just doesn’t appear) and I cannot purchase items - with real money - from the pc client or webstore. If anyone knows a fix that would be greatly appreciated. I don’t mind spending a little on this game here and there, and having a way to get a little discount or send a gift to a guild mate would be amazing to have. Thank you all!

My ally code is 281-312-152 if it is needed
