How do you properly save on the free version so it shows on your phone screen?

I've searched the site and I can't seem to find an answer. I feel like it has to be fairly obvious, and probably user error but I'm at my wits' end.

I created a widget (very simple one), clicked save and when I try to leave the app it asks me to cancel, discard, or save. I click save, and it takes me back to the widget I was working on. I click the floppy disk icon to save and try leaving and I get the same message. I exported the widget, hoping that would work and it does show up in exported but nothing is in backups. It's marked as PRO so I can't do anything with it.

I just want to know how to get the widget to show on my phone screen. I'm currently using a Samsung s8 and it is up to date. Please let me know if you need more information.
