Free version yes.
I understand it's a private enterprise, but no other service i have ever used has had daily pop-ups for upgrades.
Once a week is understandable, but this is just trying to grind away at my will for a paid service i don't need
It happens almost daily that i get popups on my desktop and mobile for upgrade options. I don't need to upgrade and it's getting spammy.
Is there an option to turn this off?
