So my app accepts a URL (Open In Place) from the File app in iOS11 and turns it into a bookmark so I can open it again later. Works most of the time except when the bookmark is for a Dropbox file that was previously conflicted. Attempting to resolve the bookmark data will hang in the URLByResolvingBookmarkData call. I can only assume the Dropbox file provider is having issues. Only solution is to uninstall the Dropbox app!
Anyone else seen this kind of thing? What kind of design lets one app hang another!
