Unable to open Team Projects in Premier CC, "must be signed in to Adobe CC" but I already am.

Following the instructions to "Remove Adobe User and Adobe App certificates" should remedy the error message "This machine must be signed in to Adobe Creative Cloud to use Team Projects." issue.

I had this same issue this week with Premier CC2020 and I was able to resolve. What I believe happened was I had myself signed in to Creative Cloud on two different machines. I closed down all my CC Apps, Premier, AE, Photoshop, etc, went in to my Adobe account on the web, found the Privacy tab, I signed out of each session, I signed out and closed the Creative Cloud desktop app, re-opened the Desktop app, and signed in again. 

Once I did all of that, I opened Premier and was able to get in to my Team Projects. I hope this helps. Perhaps check and see how many "sessions" you have open within your Adobe account on the web.

Hi -

Sorry to hear about your problem logging into Team Projects on your Windows system. Let's take a look at what your logs think is going on...

Here is where we create log files for Team Projects for both Mac and Windows:

================================

Win - C:\Users\<USERNAME>\AppData\Roaming\Adobe\Team Projects Local Hub\

Mac - /Users/<USERNAME>/Library/Preferences/Adobe/Team Projects Local Hub/

Note that your Windows system may not have anything in this folder since you are not able to connect - but let's check just in case we are able to get some feedback there. If you can zip up the contents on both your Mac (and potentially Windows) systems and send those to me we will take a look and see if anything stands out.

You can send them to me at mgoshey@adobe.com   Please rename your zipped file extension to be ".pdf" instead of ".zip". 

And now some basic questions (apologies if these are obvious but it's core info that is useful).

1. Are you using the same Adobe ID to log in on both systems? Do you have more than 1 Adobe ID?

2. Do you happen to also have a third system with Premiere Pro installed currently?

3. Please send me your Adobe ID in the email you send me - I can look up your account and see if anything odd is going on there as well.

4. Have you ever had Team Projects working properly on this Windows machine or is this the first-time ever install?

5. Are you able to use any Adobe Cloud Services on your Windows system?  Do Libraries show up? When you click on the grey cloud icon at the top right of the Creative Cloud desktop app does it show "File syncing" with a green checkmark and "Up to date" status?

Thanks!

Michael

Sorry, you are having trouble with Team Projects on your windows machine!
Does the issue still persist or did it get resolved? 

Thank you,
