It took 5 tries, but I got it to work. The 1st 3 tries just plain failed with a “Failed” message when I connected to the cam’s wifi and tried to switch back to the Wyze app. I didn’t get to the password creation step, the app was already back to the Home page and I had to select the cam again.
On the 4th attempt, I successfully created a password but travel mode automatically disconnected for some unknown reason. I never did get to the location permissions step, so I went into Permissions Manager and gave the Wyze app the location permission “When in use only”. I then selected the cam in the Wyze app and got a white screen with animated working icon in the middle in place of the Live Stream. It sat there for 5 minutes and an error message popped up. Unfortunately, the text was white on a mostly white background so it was literally impossible to read! 
5th try… I killed the app, powered the camera off, started the Wyze app, selected the cam, enabled travel mode in settings, powered the cam up, immediately got the message “Travel mode enabled” without doing anything else, skipped the app step to double-press the sync button and pressed the “Go to WiFi Selection” button on the next page, selected the wyze_camera_xxxxx network, selected “Stay connected” on the “Internet may not be available” message popup, BOOM! Connected and I didn’t even get to the password step.
I took a photo, a video, did a manual recording, a time-lapse recording and verified that each worked. Hit the Exit in the upper left corner. Heard the “Travel mode disabled” voice on the cam. The cam’s network disappeared and my phone automatically connected to my home’s WiFi.
6th try… Powered the cam off with the switch in the back and powered it back up. Selected the cam again, heard the “Travel mode enabled” voice, connected to the cam’s wifi network, BOOM! Connected without doing anything else. Hit Exit in the app and heard “Travel mode disabled” from the cam. Phone automatically switched to my home network.
7th try… Went into the phone’s connection settings > Advanced > Manage networks > deleted the wyze_camera_xxxxx entries. Back to the Wyze app, selected the cam, tapped the gear icon, tapped Travel Mode, turned the cam off and back on, double tapped the sync button, heard “Travel mode enabled” from the cam, tapped the “Go to WiFi Selection” button on the app, selected the wyze_camera_xxxx network, entered a password, tapped Connect, selected “Stay connected” on the popup, back to the app and it was already Live Streaming. Now that’s the way it’s supposed to work! 
I know that was difficult to read. Did anything stand to you that you may have missed during your attempts? Did you get to the location permission step? Did you ever get the “Internet may not be available” message popup where you select “Stay connected”?
