I'm on a Galaxy Tab A and have just downloaded the app. When I select "Start a screenplay" and it takes me to next page, it won't allow me to select "save". It says "MyScreenplay.fountain" and won't let me save it at all. I've tried changing the file type, I've checked the settings and have looked here but can't find any answers.
Choose a place to save the file.
Sounds like you need to select WHERE you want to save the file, and the default location on your device is possibly read-only. Swipe from the left and you can choose to save to a location on internal storage, or if you have any cloud apps (such as google Drive), you can choose from them as well.
Hope this helps!
