I bought my Acu-Link internet bridge in Nov. 2015 and it worked great. Then my iPhone app stopped connecting to the server sometime in December. I stopped checking it on my phone because it never seemed to connect. Then I saw an email communication from AcuRite saying that their servers had been overloaded from the holiday sales and I figured I would wait a while. Here it is March 5 and I finally decide to check it out. I went to google and it took me a while, but I saw a review that mentioned an issue with the iOS app and the HQ sensors. I remembered the HQ sensors being in my dashboard but I had deleted them from my app. Finally, I uninstalled the app and while reinstalling it I read the reviews on the iPhone app. Right there in the first review I got the fix. Worked like a charm. I went to the MyBackyardWeather website and in the upper right where it shows my email id, clicked on the down arrow and then on Follow My Friends Bridge. I clicked the red X to remove the HQ bridge and now my iOS app works again. Shame on Chaney Communications for not fixing this bug.
