Latest updates cause a problem when creating a New File. The history of past artboard sizes is being wiped out on startup leaving only preset formats to choose from. I do not use any of those, I often use a 50"x100" to design in and would just click on it when needed in the large pane. There is now not even an option to customize the new file unless you choose one of the useless presets and modify it, this slows down production and is annoying as ****. This appeared in the update yesterday and is still there today- I am running v29.2.1
