After the Trimble R1 receiver is connected to my iPhone 8 (verified in Trimble's GNSS Status App), I want to specify in Collector to use this receiver to provide GPS locations. However, in Collector - Settings - Location -Providers, it only shows Integrated Receiver is being used. When I click the + sign, nothing shows up and I can't find the R1 receiver. I have tired it on iPhone 6, 8, and 10 as well as iPad Pro and also tried to wait for at least 30 mins for each test, the problem stays the same on all iPhones - no extra receiver can't be shown in Collector (see attached). However, when I tested it in Windows, it works fine. Please help me to fix this problem ASAP as 90% of my students need to use iPhone to run this App.
