What is going on with pricing and packaging?

Is it just me? I subscribed to "GaiaPro Yearly" through the Apple App Store for 10 years now and it will renew again later this month (April 2024). Lately I've been getting many "come back to Gaia!" emails that say that they are sorry I've cancelled and I should come back for a discount. But I didn't cancel. When I follow the link for the discount anyway, it just dumps me onto a pricing page where there is a "Gaia GPS Premium" membership (not "GaiaPro"). If I click the button for "Gaia GPS Premium" it tells me I can't do that unless i first cancel GaiaPro through the app store. So...

1. Is there a difference between "Gaia GPS Premium" and "GaiaPro"? "GaiaPro" appears to be about $8 cheaper per year through the app store than "GPS Premium" through Outside directly.
2. Why do they think I've cancelled?
3. Are they discontinuing older App Store purchased memberships to force us to go through Outside?
