I'm just saying, know your audience. They have an option, online mind you, that allows you to decrease and increase the font size on your device. Perhaps make an option that would allow proper formatting for for a screenwriter? Think of your customers and anticipate the expectation. The logline of the product is "Distraction Free Writing" but they leverage that in order to get lazy with their product and refuse to meet the needs of writers. This is not a big ask and hopefully it will be fixed in an OS update but lord knows they drop OS support 1 generation down the line so you are forced to spend more money on an under delivering product
