UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Â Before I release it, I will make sure that everything is working properly and then I will release it.
Hello,
I'm struggling to understand why the satellite rejection doesn't work properly when I apply a x2 drizzle (droplet: 0.5, scale: 2.0) whereas in classic interpolation mode with the same rejection parameters it works perfectly.
And this applies regardless of the type of integration (average, auto).
The stack is 53 images of 300s each

You haven't said how many dithers you have done, but even if you dithered every frame then a 2x drizzle with droplet size 0.5 is a lot to expect from only 53 dithers. I don't usually push droplet size below 0.8, and I like to have at least 60-80 frames/dithers. I suspect with such a low droplet size you are just not getting enough data in each pixel for good rejection.

@connor231 Thank you very much, John, for your reply.
I only have a rough idea of how drizzle works. I set this droplet value based on the help pop-up for the scale parameter.
I usually do dithering every two images. That gives me about 26 dithers over the entire sequence.
I'm going to continue my tests by playing with the droplet parameters, starting from 0.8.
Your welcome Francis
I'm no drizzle expert either, but once you've had a few failures and a few successes you get a feel for what it can and can't do. But remember it is a noise injector and needs lots of frames/dithers - the more the better.
For a normal (non-bayer) drizzle with a mono camera my starting point is drop size 0.8 and scale 1.5. Often that's where I end up as well. It does depend on whether your aim is to get a larger image or fix up 'blocky' stars.
If you are planning on using drizzle you should probably dither every frame, unless your mount can't handle it or unless you plan on hundreds of frames.
To be honest - I'm still trying to get my head around best practice for Bayer drizzle. But I only use a OSC camera for widefield, so I'm usually only drizzling to get rounder stars - so I can afford to use conservative settings.
