After collecting a point, the display confirms the entered point, then offers a button to update the point (see first attachment). There doesn't appear to be any way to clear this display other than to send the point, which doesn't work offline.
Reverting to online, I send the point, then a display would appear offering the opportunity to edit the point that I just sent (see second attachment). Fortunately, that display could be closed and I could move on to the next point.
Reproduced with a point layer created this year and one from a few years ago. I am the owner of the layers.
I recall Collector having a much smoother interface a few years ago: I could enter points quickly while offline, and then upload them all at once back at the office. Is there a setting that brings back the older style? The app is currently configured for downloading only via Wi-Fi and with automatic synchronization off.
