Thank you for posting your question @realistic_maker987c, and thanks as well to @kglad and @Victoria Bampton LR Queen for their suggestions.
I understand how frustrating it can be to complete the sign-up process and not receive the expected confirmation email right away.
I checked and can confirm that a Lightroom subscription was successfully started on September 15, and a confirmation email was sent to the email address associated with your Adobe account.
If you haven't already, please check your spam/junk folder and any email filters that may have redirected the message.
More importantly, are you encountering any errors or problems accessing Lightroom or your new subscription? If you're seeing an error message, having trouble signing in, or are unable to access any paid features, please let us know what you're experiencing and we'll be happy to investigate further.
You can also verify your subscription status by signing in to your Adobe account:

If you have any additional questions or would like to share more details about what you're experiencing, please reply to this discussion thread and we'll be happy to help.
