Autocomplete not working on web form from phone

Hello, I have a survey with a question with the autocomplete setting, to search from a long list of names. It is a select_one question type. The autocomplete works well from the KoboCollect app and from the web form when accessed from a computer, but not when using web form from a phone (either online or offline). When you start typing, the list does not appear. If you manually enter an answer that is not in the list, it will generate an error.
Any insights or tips on this?
Thank you!

The autocomplete should work with Collect android app and Enketo. However, the same may not be supported as expected in Enketo with a select_multiple question type.
