My characters on create a story don’t save

I’m on my phone,trying to create a story but when I add characters they won’t save,and when I try to add new ones it says try again later and I did but the same thing happened

I haven’t directed too much on my phone cos it’s really jumpy and it doesn’t work too well for me, I’d recommend the portal, coding does take time to learn but it’s all worth it by the end

Ok thanks
