Hey Lizhorne,
Sorry for the delay in response.
We see that you are a subscriber of Adobe Send & Track subscription. There is no change in the service, just the access has been changed.
Basic functionality to send files will continue to be available as part of an Adobe Document Cloud free account. Full sharing functionality to send and track files—including personalized invitations, large documents, images, and audio and video files—will remain part of Adobe PDF Pack, Adobe Acrobat Standard DC, and Adobe Acrobat Pro DC .
Please refer to the new experience of Send & Track which has now been changed to Share & Track.
Share and track PDFs online using Adobe Document Cloud
Hope this helps.
Regards,
Akanchha
