To what Email adress did you set It for Castle to send It a verification, to your parent's or your email? If its your email then just open the Gmail app and change to the email account that should have been sent the email, if It still doesnt appear, try refreshing, now, if you sent it to your parent's email, you have two options: 1: explain to them the situation and hope that they Will let you use their phone to fix all of this. 2: Just ask for their phone with an excuse of maybe like "my phone ran out of batery and i need to search something important" or something like that, hope that they Will let you search that and just fix It. Id recomend doing option 1 honestly, you avoid getting Scolded.

Wait this is a real thing?
