[#1]

Questions:
1) Does current version of AEP Mobile SDK suport "Remote Cached Offer" ?

2) Does current version of AEP Mobile SDK suport "Remote Dynamic Offer" ?

3) Does lagacy 4x Mobile SDKs work with both types of offers ?

Documentation only describes how Dynamic Remote Offer works for HTML page, but how it works with Mobile SDK I can not find any information.
