Hi Mark - yes I think you are right. At this stage, we are still in the analysis phase to test which tools will give us the best result when building fully responsive courses. We are open and willing to test and try all the options.
Since our LMS is built in-house there may be a lot of non-standard requests, as Wes pointed out as well.
Our next step/test is to replicate the course we built using Evolve using Adapt. For that, we will need, as you mentioned, an Adapt developer.
That was my goal for posting on this forum.
