I see the account you used to post for help is free. Our system let me know you have two Lightroom accounts, and your other account is subscribed. I will send more info in a direct message to protect your privacy.
Once you sign into the subscribed account, please look at the app Settings > Premium features to see the premium features that come with your Lightroom Mobile subscription.
Also, I see your post tagged MacOS and Windows. Your Lightroom Mobile Premium subscription works on iOS and Android, and any web browser at https://lightroom.adobe.com. Mac and Windows apps are not supported with your Mobile Premium subscription.
