Realms Glitch

Now, Mojang, don’t yell at me like,“Hey! This is supposed to go on bugs”, because I have to CREATE an account and I am small person and can’t do it. Anyway, the realms glitch. I can’t access my inventory in my dads realm for some odd reason. UNLESS, he is on at that time. I think it may be the new marketplace that messes this up, because you peoples COMPLETELY redid it (it looks very nice by the way), and the realm stopped working. I don’t know if Minecraft is supported on iPhone 6+ or not (that’s what I’m on), but if it doesn’t, please do it, my parents won’t get me anything higher than that. Thank you!
