Welcome to the Forum, @stanlam! 
I’m glad you found something that works for your Cam v3s, but Cam Plus Lite is not supported on Cam Pan v3 (the subject of this topic, according to its tags). According to the most recent Fix-It Friday update, Wyze is still tracking this issue, and I believe they’ll have to supply the ultimate fix.
I like your detailed instructions, too! I genuinely hope that your solution helps others with Cam Plus Lite subscriptions experiencing this issue on Cam v3s.
