Review coming shortly.
I have just reached out to Naster on Telegram and paid (via PayPal) for a 3-month subscription. He will provide me with an account within a few hours, and at that time, I will amend this post with my vouch, if the subscription works as advertised for all products within the creative cloud suites.
Naster was very communicative and informative, and answered all the questions I had in a professional manner. Stay tuned for a vouch!
Just received my invitation within a matter of minutes, not hours! First of all, the invitation message and signup pages were in German, which wasn't a big deal... Just fill in the [obvious] fields and hit the blue buttons, and once accepted and registered, your Adobe control panel displays in your the language of your preference (according to your own Adobe account).
I used a freshly-created email account to register with Adobe, and after accepting @Naster's invitation, my account displayed a team subscription!
I just opened every app (that I have installed on my computer) in the creative suite, and all opened without any issues.
There's nothing else to say about the account except that it works as it's supposed to! I am currently updating all of the apps through the Adobe Creative Cloud app without any issues.
My general experience with these accounts in the past is that they last a month or so before they're disabled. I purchased a 3-month subscription from OP, so I will update here regularly with the status of this account. Cheers, and I'll report back later!
