Here are some hints for trouble shooting this:
1) Check RS settings and make sure it is set to send your beacon to SN and has your username and password. Turn on location (make sure you get the blue circle). Turn off radar selection (radar abbreviations don't show). Turn on showing spotters and make sure you see other red dots.
2) Keep RS open and active in the foreground for a while (RS does not beacon when in the background)
3) On a computer open this file in a web browser:
https://www.spotternetwork.org/feeds/gr.txt. If you did steps 1 and 2 correctly you should be able to use the find function to find your name in that file. If you don't see it you are either not beaconing or have been disabled (usually due to not having a phone number for NWS or for violation of SN policy). If you do find your name in that file, you should also be seeing it in RS. It might also be helpful to login to SN from a web browser and check your position history.
