How are you accessing Todoist on your mac? Are you using the web app, the Chrome extension, or the mac app? You can download the mac version right here. https://todoist.com/mac
Make sure you are signed into the correct account on all plugins/apps that you are using. You can log-out from the TD icon on the top bar on your mac.
Same problem from me. For example, there is no "add note" button at the bottom side!
You are showing up as Premium on my end. As stated above, make sure you are signed into the correct account.
You can also try to log-out and back in again. If you believe you are signed into the correct account, does this only happen on the mac application, or is there a problem on the web version as well?
The key here is that you have to close down todoist, and re-open it. Please add this to your instructions.
