The explanation is simple.
Xenia worked until spring 2019 with Ewa. Since, everything Ewa posts is old content and also little teasers that she made with her smartphone during the shoots.
Anything Ewa announces as an update is just old content (Like Score and a lot of sites do)
In the fall of 2019, Xenia started her Patreon. Looking at the rates offered at the time, it was clear that she was looking more for a wealthy man who could meet her needs ($ 2,000 a month just for his smile OMG!!!) than to please his fans. Coincidentally, she removed this tariff at the same time she stopped updating.
She made some very random updates every now and then with very poor content. Even the professional photos were so much photoshopped that it could be seen with the naked eye that she had been thinned and her skin extremely smoothed.
In the summer of 2020, she stopped updating (the last date of early June)
In the fall of 2020, Xenia officially announced (i can't remember on which site) that she was ending her career (has she ever started it ? lol).
The Twitter and Facebook accounts are managed by Ewa, she is still trying to get more money into the cash registers by posting some old, more or less unseen photos. There have been two Patreon accounts, one managed by Xenia and another by Ewa. Both only offered very old content.
Since then, it seems that Xenia has grown fat and found a rich Arab but we do not know if she shows him her breasts.
I've had a few conversations with her on Patreon when she opened it. She had nothing to talk about, nothing interested her except money, and she said with some pride that she had no qualms about making her fans believe a lot. It’s really not a loss for the big tits business.
