Hi Malinda, Strange. I updated my Collector version to 18.0.3 back in early August on my Samsung S9, and all seemed well. A few weeks ago, I had trouble opening web maps in Collector. I would click on a web map and get the swirl of death, nothing would open. I uninstalled Collector and reinstalled it. Same version, build 1033. My web maps were listed, I could open one, and add features. I just tried it again now. I don't know what might be different between our setups. I would try the uninstall/reinstall and see if that clears things up. I am afraid I am not much help. Let me know if you are successful, Thanks, Jay
