as the title says i have the app on my iphone 15 pro max and for some reason its not letting me even enable the roll dice option in the create character sheet and i was wondering if there was a fix for it or just something im missing

Update the app perhaps?  I have the 13 Pro and it works fine for me, verified a few moments ago.

im gonna try and see if i delete the app and redownload it helps because the app is up to date and everything because i had my friend download the app and he could roll perfectly and when i signed into my account onto my partners phone i could also roll on there

Hope it works for you!
