This app doesn't let you save any changes to pdfs without making an account. The sign in/create account buttons also don't work. But really, it's kinda lame forcing you to make an account in a way that makes 90% of the features useless if you don't (because what good are the features if you can't save them). Will be finding a better app

Hi there, I'm sorry to hear about the experience you've had with Lumin. Lumin requires an account because it is a cloud-based platform designed for auto-saving and syncing. We would love to talk with you more to resolve these issues. Please contact support@luminpdf.com so that we can investigate the issues you've experienced.

so far it's working good. I'm trying to annotate beyond the first page and it's making me choose a different font but overall I'm happy to be able to edit a pdf. I can work with this

I have canceled this app and then they charged a $30 fee. It was canceled in advance to avoid this fee. I want my money back.
