I was building out a monk on my phone when I noticed I could not add stealth as a skill proficiency. I have some pictures I can add but I’m not sure how to add them on mobile. 

Hi Lothsun,

Could you please link the affected character sheet here? Use the direct URL from the address bar, and not the share link.

Thank you!

Check your race and background. There are races like Tabaxi that add it as there are backgrounds like Criminal. 

You are correct. I used the autocreation to create the character and it was selected under race. Thanks for that info.
