I have had my htc one phone for several months now. Recently, I went to install an app from the Google Play Store using my desktop computer to "send" the app to the phone over wifi. I clicked "install", went the listing of my registered devices...I have 4...but only the htc one is actually activated with Verizon for phone and data services. The others I just use as media players, cameras, etc. Anyway, all devices BUT my htc one shows up in the listing of available devices! Why did Google Play delete my phone? I CAN access and install apps using the PHONE itself from the Google store! How do I get my phone back on the listing of devices via the web based Google Store on my desktop? Does Google limit the number of devices one can have on a single account? Thanks!
