Hi, we recently upgraded our Desktop users to Desktop 10.5.0. We also upgraded the License Server Administrator to 10.5.0. As I am new to a lot of this, I was looking around and noticed our ArcGIS for Server and the WebAdaptor are still at version 10.4. In the past two weeks or so, we have been experiencing issues using Collector (latest version) on Windows 10 tablets (basemap loads, editable layers do not, and the error cites our webadaptor URL), but we cannot nail down when this may have actually started (as the tablet addition was fairly recent). However, we do not encounter these errors on iOS tablets using Collector. With my inexperience, and seeing the webadaptor URL, this has me wondering if we need to upgrade the Server and the WebAdaptor to 10.5.0. And if we do upgrade, will we have to republish all of our services? Thanks!
