Please refer the below article.
Note: Student & Teacher educational memberships purchased from Adobe.com, Amazon.com, and other third-party retailers (excluding Kivuto) aren't affected.
Thank You! I have reviewed the article. I contacted Adobe by phone and ordered my S&T membership. never went through a third party. So now what?
We have checked the Subscription SKU which you bought from Adobe and its completely fine and eligible for Lightroom Mobile, we have sent your details to back-end team to correct this issue.
We will notify you once we received any reply from them.
Thank you so much. I am teaching Creative Cloud and our Exams are this week.. part of the exam has to do with Lightroom and I need my LR mobile to share. Again, Thank you so much.
