I lost a lot of tokens trying to generate the same image multiple times because it kept freezing. This is the reason for my disappointment and for canceling my subscription. I am a professional fashion photographer, and I must admit that Lupa Upscaler is an excellent software so far. However, the problem is that once the credits run out, there’s no way to buy more until the end of the month. For my profession, that’s not sustainable. I’ll definitely look for other solutions like Topaz Gigapixel or others. What a shame!
