Complete Reference for D&D

There is an issue with the Dungeon Generator in the DM tools. It'll allow me to generate the dungeon, but whenever I got to save one, it hits me with "this app is not allowed to write to your storage". I've checked that all permissions were enabled and I still receive the error.

For note, I am on ...

Would it be possible to add Echo archetype for fighter? It's on 5e character creator app but not reference guide. Thank you in advance
