Hi everybody, We're going to rework the structure of the XR forums in the next hour. For this purpose, we will set all forums in the XR section to read only. Update: We have encountered a problem with our forum software in which forum threads are not showing up, despite the fact that the thread and post data is still perfectly safe in our database. Threads that were previously in the Handheld AR, ARCore and ARKit forums are currently affected by this. Once recovered, they will show up in the AR forum. We are working on recovering the affected threads and will continue to provide updates about the situation in this thread. Thank you for your patience! Update: All threads that were previously in the Handheld AR, ARCore and ARKit forums have been moved to the AR forum to reduce complexity. The XR forums are open for threads again. Further work on the XR forum structure is planned for Monday.
