Ok, so I figured out that the first chat request we sent at 7:03 am didn’t complete properly due to a pop up/content blocker installed on my web browser. I use Purify, which must not play well with Disney.com, though I’ve chatted on plenty of other websites with no problems.
It may be useful to add “Disable all popup and content blockers” to the tips on the first post - to hopefully help someone in the future.
Still waiting for a CM to join the chat window we opened from another device at 9:30-ish. Maybe we will have to try another day when my brother is not at the group home.
Update:
It took a long time, but we finally finished with success. Wait time in the first chat window (opened at around 9:30am) was about five hours. The first chat was a very short screening session. Then we waited 10-15 minutes more to be connected to the video chat CMs. Unfortunately the first attempt at video chat had to be abandoned due to technical difficulties. Mom was given a “secret code” to use to skip the long wait and first screening chat next time. Tried this a half an hour later and everything worked great.
For the advance planning selections, we got all the attractions we requested during the timeframe we requested. One of our dining reservations did conflict with a ride window, and luckily I was able to adjust it successfully. All in all we are very happy with the scheduling.
Most of the wait and the problems we experienced could have been avoided had I realized sooner that my adblocker was blocking the chat window. Live and learn.
My advice is:
1. Disable all VPNs, adblockers, and content blockers before beginning.
2. Set your device’s screen to never time out or auto lock.
3. Request your registration chat right at 7:00am. Be sure that the chat window opens and starts properly. Set aside several hours in case things don’t go smoothly.
4. Open a second
MDE tab to use for logging back in when MDE logs you out - every 30 minutes. I found a timer helped me to keep track of when a logout was about to happen.
5. Keep your device within sight and check it often. We did not receive any audible alert when the CM joined the chat.
6. Be patient. The CMs are extremely kind and helpful once you get connected. Despite the time it took, I am very happy we did the advance registration.
