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.
When I stack/integrate subs with APP it never rejects a single sub. No matter how many lights insert, even some with vastly lower quality than others (i.e. blurry stars) APP will simply integrate everything.
So, I did a test and used 205 subs. APP integrated all of them without rejecting a single one. Mind you, dozens of subs were really poor quality.
Then I did the stacking and integration in PixInsight (WBPP) - and PixInsight rejected 77 (!) subs.
The result of course is that the final stacked images from PI came out of much higher quality than from APP.
PI also handled the flats/darkflats much better (I have a pretty terrible spot on the camera protection glass (I hope)) and that spot was basically "erased", while APP botched it completely and dupplicated it, creating a pattern of "spots".
I have not changed any settings when integrating in APP, that is, I use the default settings and just go directly to the "Integrate" tab -- APP then runs through the whole routine of registration, calibration etc.
But I always wondered why some options, e.g in "integrate" tab are greyed out, like (I think, I cannot check right now) the option about LNC rejection or something.
Most of those are greyed out - which is why I always thought APP simply does not use that, which in turn is why from the same set of 205 subs it did not reject a single one, while PI rejected 77.

I have watched all APP tutorials etc. - but most don't actually go into detail what should one select in each tab, i.e. what about those "normalization rejection" or "lnc" or whatever parameter - in all videos I watched they just brush over them like "you don't need to change anything here just leave it as it is". Well, apparently leaving as it is is the culprit because then I have the feeling none of those functions are being used at all.

Yeah, I tend to agree that with all the analysis that APP does, it could make a pretty good estimate for rejecting shots. In the Integrate menu, there is a slider to reject a percentage and then it will reject the worst. However, what I do is Normalize, then view the analysis graph and reject outliers. Then I go on to Integration 100% of the remaining shots. Works pretty well.
then view the analysis graph and reject outliers. .
How, where / what tab?
Also: I usually deal with SHO data, so pretty much do 3 channels at once.

After normalize, you can see the analysis by pulling open the window using the <> arrow buttons shown in the attachement.
