Hello,
Installing Champ could cause this problem, but only if your phone is
running something earlier that Android 4.4. That is a pretty old
version of Android, and I think it is very unlikely that you are running
such an old version, but it is worth checking.
The more likely explanation is that something changed about your
dispatch alerts and Cadpage is no longer recognizing them.
In any case, use the "Email the Developer" setting to send us a support
email right after Cadpage fails to pick up an alert. That will give us
a lot more information to work with.
Good luck,
-Ken
