For your first point where you say "reverting back to default", a couple of questions:i) do you see that you are qualifying for Exp B (based on the response from Target) but you see Exp A default content?ii) if so, do you never see Exp B content or do you initially see it and then it gets overwritte...

Could you send a screenshot of what you see with the AEP Debugger? 

If you check the Response Tokens within the Administration section of Target, do you see activity.name & experience.name with a status of Activated? If not, then by activating these you should then see the value as part of the response.However, you won't see any Response Tokens in the response paylo...

I would expect that approach to work, so I'm wondering, what is the order of operations? i.e. is your targetPageParams code executed before the global mbox call is made

It sounds like you have implemented both Analytics & Target in the mobile app and have implemented Analytics for Target reporting, is that correctly understood? That A4T integration works by sending an additional call, which matches with what you're describing. I'm also assuming you don't see the sa...

Could you provide some more detail of what you want to integrate? Do you already have Commerce & Target or are you trying to find out if there are Target-like capabilities within Commerce?

If you use the AEP Debugger then you can......i) Click "Target", select "Configuration" and toggle on "Target Console Logging":ii) Click "Logs", find "AT:response" and expand the "Execute" object until you see Response Tokens

You're right that viewName is typically used to identify state/route changes in SPAs but you can think of it more generally as a way to notify Target that content has changed. The challenge here is that it still depends on you being able to identify which card has been displayed, so that you can pas...

The two most reliable options I can think of are:i) Work with a developer to have a unique ID/data attribute added to each card, so you can reliably identify itii) Work with a developer to have a unique viewName for each card e.g. triggerView('cardOne'), triggerView('cardTwo') etc

Just to be sure, have you confirmed that you are being entered into the activity when you're in the incognito browser? Also, you mentioned triggerView, can you confirm that {page:false} isn't being set as part of the triggerView call e.g.adobe.target.triggerView('homeView', {page: false})
