For some reason a lookup field in a Lightning Web Component is not working properly when accessed from a mobile browser. Not working properly means that the autocomplete function does not work properly. This works fine when accessing the community page on a desktop, but not a mobile.

This is a Lightning Web Component with the field below being a lookup to the Contact object within a lightning-record-edit-form compenent

<lightning-input-field field-name="Related_Contact__c"></lightning-input-field>

Apparently lookup type fields are not supported by this component in Mobile...


The solution is custom component as per the example: https://github.com/pozil/sfdc-ui-lookup-lwc


This is now supported for the mobile app:

The lookup type is supported in Experience Builder sites, Lightning Experience, and the Salesforce mobile app
