Xfinity web site problem will not allow moving through a recording which is still being recorded.

The Xfinity web site problem will not allow moving through a recording which is still being recorded has been an issue for over a month. This works fine on the cable box but it is clear that Xfinity wants to make more money from their advertisers by forcing us to watch a program from the beginning while it is still recording. I think this started when the fast forward option past a commercial now restarts before the commercial and then the rest of the watched show resumes.  More money to the advertisers by forcing us to watch what we don't want to see. So many users are writing about these problems and I think this is just another reason to dump Xfinity as a provider. 

I ask the question to Xfinity. Will this will ever be fixed in the future or will they settle just to drop customer after customer for more advertising money?
