I think most people already know this but for the next 2 days Amplify will be doing maintenance or something on their website, causing you to not be able to sign in into your account.
Just making sure mods+admins don’t get bombed with ‘I can’t sign in’ reports.
Also, please correct me if I am wrong.
This would be an announcement but I don’t have permission to make one.
UPDATE: Maintenance will be ending tommorow.
UPDATE: Maintenance just ended today! Everything should be back to normal now.
I tried logging in, using teacher.desmos and everything seems to change to Amplify. I can’t find my classroom activities, can’t log in, I keep getting redirected to the homepage (Amplify).
I’ve got activities for tomorrow and I wanted to assign them today. Any help? Please.
I can sign into my account fine… it may be something with your computer or internet.
I can’t really help you since I’m not an amplify technician, but you can go to their help center.
Try going directly to amplify, not through the portal.
Try this also:
I sent a mail to the support team and it was resolved today.
"Hello Avitechnologies,
We appreciate you reaching out to Amplify Technical Support.
We have reviewed this issue concerning Amplify Desmos Math access. It seems the problem was due to the account being misclassified as a student, rather than a teacher. Our Engineering team has fixed the error and re-added the classes. You should now be able to log in.
This should now be resolved. Please reply to this email within 2 business days with any questions or concerns. Thank you!"
That was the email i received today.
So, i just checked, I can log in and my activities are intact.
Thanks.
Okay! That’s nice it all worked out for you. Your welcome for the help… even though it seems like I didn’t do anything 
that’s a pretty silly reason
