Editing PDFs in Dropbox from my iPad

[GS321]

I'm trying to edit/markup PDFs that I have stored in Dropbox from my iPad. I'm using an Apple Pencil that's capable of "markup." 

The adobe integration was meant to be the answer for this; however, Adobe is now charging extra for the ability to edit. 

Apple allows you to edit Dropbox PDFs nicely through files; however, this seems to be hit or miss as sometimes the files won't open or get re-directed to Dropbox.

Are there other ways to edit PDFs from the iPad and have it sync with Dropbox? This would seem like it should be a top priority for an added feature. OneDrive, for example, has the functionality built directly into their app. Any help would be much appreciated.

I have the same problem.  I have Acrobat Pro, and I used to be able to do this, but now it's not cooperating.  Even when I click Edit, it only lets me select and move objects, not mark up by hand.  This is super frustrating.
