Good morning,  
This problem has come up several times this year, and several times in the forum, but none of the responses seem to help. I’m hoping someone has a fix!  
My students in CSP are working in Unit 8. That is the unit marked as “assigned”. They want to access their prior work (like unit 5). When they visit those links, either through google classroom or by navigating through their [code.org](http://code.org) dashboard, they receive the message that the teacher does not expect them there.  
The unit is marked as visible.  
The individual lessons are marked as visible.  
If I try to “assign unit”, they all immediately lose access to Unit 8. Help!  
Colin

Greetings,

I am sorry to hear that this is occurring for your students. This is definitely not the intended behavior for the website. If you could reach out to [support@code.org](mailto:support@code.org), this should get routed to the correct team to investigate and to solve.

Cheers,  
Erik
