@JVanders The issue you described is a known issue with version 2.4.6. This issue has been addressed in the next version of OpenLP, that is in the Beta process at this time.
You may find that the remote webpage may help with the issue, but even the website is not a cure for the issue.
You may also find you have better results if you turn off the Cellular data during the service....sometimes the phone thinks the cellular data is better than the WiFi.
