iApp - Lessons no network + C960 analysis crash

I almost exclusively use the iPhone app for chess.com. I recently have had two issues.

I was doing all the lessons and learning a lot. But now they stopped working. When I enter the lesson "Using the initiative" it thinks for a bit then says "no network" and kicks me out of the lesson interface. I have a strong internet connection, other features of the app work. I've tried killing the app, turning off my phone, and even deleting and re downloading the app. Same result - "no metwork" when I try to use the lessons.

Second thing I've noticed is that if I try to analyze a prior chess 960 game, the app crashes if I try to turn on the computer analysis when either player can still castle.

Any thoughts or fixes would be appreciated. Otherwise maybe I am just reporting two bugs.

Update: the "no network" issue has gone away.

Edit: never mind. After playing through one more lesson it is now back.

I am also getting the no network bug. Or is it a bug at all? Is this related to membership level with a really bad error message trying to tell me to upgrade to diamond?

I can play through one lesson per day, which makes me think it is a membership level issue, with a poorly worded error message.

Anyone with thoughts on the C960 engine? A related question: any way to set up a C960 position and then play through and analyze it?

I am also dealing with the same "No Network" issue after entering the "Using the Initiative" lesson in the iApp. Someone, please advise!

I think this happens when you reach your daily lesson limit.

@flyfish-kansas - unfortunately, that is simply not the case. Both yesterday and today, I receive the "No Network" error on all Expert level lessons starting with "Using the Initiative". This occurs without having done any lessons that day.

I believe this requires a @chess.com response.

When i want to plya chess it gives error ,no network, however i have good network speed
