I am running the latest version of Djay 2 for iOS on my iPad Pro 11 (iPadOS 13.2.2)
When I start typing in the search, the results are inconsistent. Sometimes when I type one or two words, results will appear, however other times I may type in more words to reduce the number of results and I will get the “No results” prompt. The titles are clearly available as I can see them and load them from the playlist. I am searching internal storage from Files.
