Yes, speech bubbles out of screen makes it unreadable.
However stating that over and over again here won’t spread the awareness that you want.
Try to start a topic about it or a How To: or talk about it in Instagram.
As @/Scarlet_Sapphire stated even without knowing how the Guide Box works, I didn’t ignore the warnings. But it didn’t make sense to me until I tested my story on a tablet and some phone users don’t have a tablet. When things don’t make sense many choose to ignore, when they shouldn’t.
What makes a story unreadable for me besides the points I expressed months ago, is when MC does something out of character with no coherence, what I mean is for example she is described as a goody-shoes and out of no where she starts killing people or she is ruthless, the guy comes and she becomes all mushy mushy
