Zotero iPhone App - search not working?

Inwes

Hi, I have installed the iPhone app and added one reference - the info part only, including title, extract etc., but not the actual pdf. In the search it does not find any words mentioned in the title or the extract or any of the tags I created. Am I missing something or is this a bug? Could anyone please help?

My phone’s iOS is up to date.
Many thanks in advance,
Ines
