Error message in Progress Sharing with Class Code

[Lora-Marie1]

A couple of my students have shown me their attempts to enter our class code in the Settings' "Progress Sharing." I have a screenshot showing the error message atop the background showing French I and the correctly typed code. There seems to be no way to email the folks that write/update the Duoling app.

Thanks in advance for any help!

You might let them try https://www.duolingo.com/settings/schools in the browser of their phones instead of in Duolingo's app.

Note:
Duolingo is designed for the latest version of the Google Chrome browser.
I prefer the Firefox browser.
