Ok.. New test session started
iPhone 5S broadcasting remote events/iPad Air and iPhone 4S following all under same account:
iPad Air and iPhone 4S both sent requests and were accepted by the 5S. Devices connected and the number on utility bar icon correct.
iPad Air following successfully, but no response on iPhone 4S.
Tested iPad Air switching apps, reconnecting, and resuming follow. Success
Tested iPhone 4s even though it was not following correctly with switching apps, reconnecting, and hopefully starting to follow. Other devices noted the change on the utility bar icon when the 4S left the screen and when it returned, but still not following correctly.
Hit the power button on 4S and then brought it back to in app state. Connections reflected correctly on other devices. Still not following correctly.
Hit the power button on the iPad Air and then brought it back to in app state. Connections reflected correctly, iPad air did not resume follow, then took itself back to home screen. Devices reflected the "crash" drop of the iPad Air. Opened the app again after crash, no devices showing the iPad Air as back. Device linking screen no longer has "Stop following" message. Tapped Follow: BOTH the 5S & 4S are listed as available. Tapped to connect to the 5S again. Devices connected updated, but request did not show on 5S. Following did not resume on iPad until I navigated it to the same set list screen.
Tapped to stop following on iPad Air. Other devices did not reflect the drop of the iPad Air. iPad Air now shows "Follow Remote..." but still shows other 2 devices as connected beneath the selection. Re-Followed on iPad Air as I did when it "crashed" in last step and it resumed follow without prompting broadcasting device again. I see that as a plus. This time, follow resumed without having to navigate back, but it left a ghost image of the device linking pop up. I tapped the utility bar icon and it cleared the ghost image and kept following.
Tapped to stop following on 4S. Attempted to resume follow to see if that would trick the 4S into following. Other devices still showing 4S as connected, but "Looking for Other iPad, iPhone, ..." screen never lists an available device, just apples working icon spinning.. waited 5 minutes.. still spinning.
In previous testing sessions when attempting to switch the broadcasting device to see if it would help: Even if I stopped following on all and turned off broadcasting on the originally broadcasting device, all devices seemed to not disconnect completely. To successfully set up a new broadcasting device, I had to close the app on all devices, reboot all devices, and then wait a few minutes before setting up the new broadcast. Even after closing app and rebooting devices, if I did not wait a few minutes, I would either not see available devices or not receive requests on devices that did find the broadcaster.
I hope that you were able to follow that. I've read the instructions on linking numerous times and feel I have a very good grasp of how to operate it. I'm just not able to get it operating consistently and dependably. Our group tried the broadcast screen option, but with different size screens and resolutions & tempo's not being synced.. we decided Remote Control was the way to go. When it IS working, whoever kicks off the song uses the metronome flash and the rest of the group ignores it. It's just very frustrating when something in the following chain ceases to function and we have to close all apps, reboot all devices, do a couple songs without the app, then re-initiate the whole thing.
