Upgrade StorageAuto metadata for PDFs on iOS
The [documentation](https://www.zotero.org/support/attaching_files) says:
>If you save a PDF directly to your library, Zotero will attempt to retrieve metadata for it and create a parent item automatically. If the item can't be recognized, you'll be left with a standalone attachment. You can add a parent by either saving an item from the web and dragging the PDF on top of it (if a PDF isn't attached automatically) or by right-clicking on the PDF, choosing Create Parent Item, and entering an identifier such as a DOI or ISBN. If all else fails, you can click Manual Entry after selecting Create Parent Item and manually enter metadata for the item.
However, the iOS version does not seem to either attempt to retrieve metadata and create a parent item automatically from an imported PDF, or to be able to look up metadata from identifiers when choosing Create Parent Item.

Or any suggested workaround e.g. through the web interface?
I am using my iPad app but just because of this lack of functionality I need to wait to sync with my laptop library, retrieve the metadata there and then only use correct citation. It often takes day or two before I reach my laptop while travelling.
I noticed that arxiv.org is supported (obviously).
By "supported site" you mean one of the websites that have a translator[1]?
I.e. one can check if the website is supported [1] and then only figure out which is the corresponding site for the pdf link?
[1] https://github.com/zotero/translators/ ?
When you go to save a page to Zotero on iOS, you can see the translator being used at the bottom of the save sheet, and then it will show you whether it's attaching a PDF. That should just work on the vast majority of publisher sites with article pages.
You can also see from the icon whether it's saving a journal article, webpage, etc.
If a site isn't supported and it looks like it's just saving a webpage, you might want to go and instead save the PDF directly and try to retrieve metadata later, or if there's a DOI in the PDF you can paste that into Add by Identifier in the app.
