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.

this is wicked convenient when someone sends you a document that you otherwise couldn't edit or add your signature too. only downfall is the pricing, while it's worth what they ask for someone who doesn't have wiggle room in the budget it's difficult. there's a 3 day free trial so I've used it twice so far and it adds your legit signature

I don't understand why I must sign in to save annotated documents or why Internet is required. I found a link that says it's not required but if that were the case then why is it not intuitive or even obvious? why is it something I have to navigate to to activate?
