Custom Slide Variables Work On Desktop But Not Mobile

Hey, so I have recently been looking at upgrading from Articulate Storyline 2 to 360/3. However, we have some custom code in our LMS.js file which allows us to pull custom slide variables from our slides and store them in the database something like this: 

case "BW_StoreQuestionResult":
 var player = GetPlayer(),
 id = arrArgs[1],
 slideId = player.GetVar("slideId"),
 criteriaId = player.GetVar("criteriaId");

 var modifiedId = "";

 var dollarSlideId = slideId.replace(/ /g, "$");

 var dollarCriteriaId = criteriaId.replace(/ /g, "$");

 modifiedId += dollarSlideId + "|";

 modifiedId += dollarCriteriaId + "|";

 modifiedId += id;

 arrArgs[1] = modifiedId;

 RecordInteraction(arrArgs);

 break;

This works perfectly in Articulate 2, and on desktop for Articulate 360. We have an issue where this is not happening on the mobile player however, I am assuming that there is a separate script file for recording interactions on the mobile player.

Is there a way to get variables from the player for the mobile player in articulate 360? Until we can resolve this, we won't be able to upgrade to Articulate 360. I will attach our modified lms.js file.

Thanks

Will
