Yeah, I got a refund, no questions asked.
I have noticed what you describe as well. Her captions and prices have both changed a lot these last few days. Before, she would also post 2-3 times a day (including stories), but not anymore. So either she has changed the person who runs the account, or they have decided on another way forward, as you say.
I actually think that her OF was okay between June 2020-August 2021. Yes, the captions were a bit misleading back then too, and the content has always been overpriced, but she actually posted good content for the most part, and none of it was recycled unless you hadn't bought it before. Seeing as I bought pretty much anything she sent instantly, I didn't have any issues. Towards the later part of 2021, though, I also started to receive old content, and I've had to contact OF between 5-10 to get refunds for things I already bought.
Everything about her OF just seems very low-effort right now, which is really unfortunate. Perhaps she feels like she has made enough money, and that she can keep going with the recycled content because the influx of new subscribers is large enough.
