Just been having some issues with saving updates to products descriptions when using Shopify 2, so thought I raise it.
If I change the content within the 'Description' editor it does update, but if I change the formatting then it's often not updating after a 'Save'. e.g. changing an H1 formatted title to H3 is not being saved, even when I go back into the Product page within the admin, it's showing the update, but the site hasn't been updated.
If I use Shopify 1 it does work fine.
Thanks for the heads up. I was just able to reproduce the bug. I'll log the bug and get this addressed soon.
