Highlights do get exported from a pdf I have in the device when I upload it in the cloud. They are there also when I'm working on a cloud document and I save a copy on the device.

This is not so with bookmarks.

Bookmarks disappear from the pdf when I save a copy from the cloud on the device (resulting in the local copy NOT having them, and the cloud pdf still having them) and the same happens when I upload the pdf with bookmarks from the device to the cloud (the cloud pdf just uploaded doesn't have the bookmarks, while the pdf on the device retains them).

Also, this is very bad for when I decide to clear user data of the app or reinstall it for a fresh start, since I lost all the bookmarks (but not comments or highlights) from all the pdf files multiple times throughout months, losing hours of work.

Basically it feels like acrobat reader doesn't save bookmarks in the pdf files, while it does so with highlights and comments. It seems like it saves bookmarks in the cache of the app, so when you open the pdf from somewhere else they're not there.

Please fix this and also please do so, so that the next updated versions of this app save bookmarks into the pdf file even if they were added in older versions of the app. Don't make me remake all the bookmarks again because one day with an update they suddenly disappear into nothingness (like they did one time), I beg you.

Thanks.
