Mine as well. It was in the list of apps to update from my APP Store icon on my iPhone. So I simply hit update all, as usual. Next time I opened the DCS App, it was updated. No data loss.
Incremental updates to apps is perfectly normal. Sometimes testing show one thing, then ou tin the field someone finds a bug. It's reported, investigated, then the developers get to work.
We get firmware and app updates all the time for our electronic music gear. Sometimes to add features, sometimes to fix a bug. Some bugs are harder to fix than others. That's why sometimes we may see some simple fixes first, then the complicated ones next.
