All right... so I see this a lot on the Tapas forum and discord, and it can be really hard to get this across nicely and gently, but I'll try. Please take this in the spirit of me trying to give helpful advice and not trying to put people down or be mean...
Tapas is a place where you are competing for attention against literal professional artists and writers. Professionals who have been published. Professionals who get paid for their work. Professionals with years of experience in their field, qualifications and often people who have placed in big competitions, spoken on panels at events or run workshops.
Succeeding on Tapas means competing with them, and it's not impossible, because the resources are all out there. You can find illustrators to draw or paint covers, or good sites for stock photos, and you can find free image editing software and loads of tutorials on how to use it, and how to make a nice looking novel cover if you just do some internet searching. It's not that hard to seek out beta readers or feedback on your grammar, or to read books or even free blogs on story and scene structure. It's easy to go and read a bunch of popular works on Tapas in your chosen genre and to make notes of what they do well and how they promote themselves.
Before you start throwing around phrases like "no matter what I do...", you need to actually exhaust all the things you could do, but haven't done yet. There are still plenty of things you could try, like improving the typography, imagery and presentation of your covers, looking for an artist to draw you something, finding a beta reader or somebody willing to give feedback on your grammar and pacing, trying new approaches to promotion. That's what people with lots of subs are doing; they give this stuff a lot of time and attention!
And if that sounds like too much, and actually you just want to write for fun and be part of a community, you need to either be at peace with having just a small, dedicated audience who are also writers and enjoy the shared act of creation and the freedom to learn at your own pace (nothing wrong with that, it's pretty nice! I hung out in places like that when I first made comics), or find communities more focused around hobbyist writers where readers don't expect such professional presentation. Sitting being miserable about low performance on Tapas while not pushing yourself to rise to the challenge of trying to make work at Tapas readers' expected professional level can only bring resentment and frustration.
