@Comdag.Andreas We always work towards making it better and available to more and more users.The real min-sdk-version is set to 14 in the apps, which does not affect any high end devices, it ensures only lower-end device compatibility.
Further, as you said about .webapp project, I would like to request you raise a support ticket, we will ensure fixing the same asap within a day if possible, as we did for each of complaint that we received through any channel. We do ask to raise support ticket as it ensures ticket closes after resolving the issue.
