I personally haven't seen her but a close friend of mine has and he said the massage was poor (compared to thai/chinese shops he uses) and he also said the h/e was poor - really lacklustre and poor technique I seem to recall.
Make of that what you will. 
If i remember correctly i believe i was the first to review Jessica on UKP not long after she appeared on our scene which was pre covid, i went on to see her maybe 4 or 5 times after my initial visit
After a number of visits i was able to get her to suck my dick and i did get a taste of that sweet pussy of hers, however this was more of a sample rather than an experience, definitely not worth the extra, i did persevere with her mainly to see if repeat visits would pay dividends but in the end i gave up
Back then her massage was better than ok, more medium to relaxing but it did not compare with most of the Thai shops or even the Chinese shop massages, i would say that it was her looks/body which brought her customers and not her massage skills
Like others have said, she then disappeared before returning, and again like as been said, her service is at the best, poor, couple this with her ever deteriorating body and looks now pushes her down a very busy list
I do think if she upped her game and offered much more then she could be a busy girl but htis looks to be highly unlikely
