Thank you for your report!
Unfortunately, we cannot provide you with direct technical support using the bug tracker site, though we will keep this report open for now to determine if it is a new bug or has been reported previously, as well as which project it should be assigned to. In general, unless you have purchased a Realm subscription where your boys are playing together, you will want to use the "MCPE" project for bug reports.
For technical support you might try the Minecraft Community Support Discord at: https://discord.gg/58Sxm23
If you want to request a refund on your purchase you will need to either contact Mojang Customer Support or the online store/site where you made the purchases.
