Has anyone had any problems with using Collector for offline editing on a Huawei P9? I've set up a map for a user but when pressing the Collect Now "+", the map closes and returns to the map gallery. The same behaviour occurs with using a long press/collect here. No new points are stored for syncing. Offline editing works on the same map on my Motorola using either one of our accounts but not on the Huawei. Any suggestions?
