A lot of creators have this issue, maybe 90% of them will experience it (from what I've seen).
If you have like 7k subs and you post a new chapter, maybe 3k will read it, you can check any author here on tapastic, most of the views they have on recent episodes won't match their subs count. Also, how do we know that those 3k that do read the episode are subscribers, chances are that part of them may not be (and that's really a good thing too).
And yet, like you say Keiii, you keep gaining followers but your views are decreasing, why, doesn't make any sense?. Well, I'm gonna give my opinion out of my own experience here and in other platforms.
Peeps don't subscribe because they read whole comic, or 1 or 2 chapters and they liked it. From what I've seen peeps sub to comics because they liked a picture, a page, maybe only the cover, they sub to read it later. If you gain a sub and go to thank that person, chances are that person didn't even read a chapter of your comic yet... So thanking right away might not be the best move, coz when they do read it, they may decide that they didn't like it (just saying).
And this happens more often to popular comics or tapastic's picks, wow this comic must be good, gonna add it, read it later. And yes, this peep wil do this to probably 50 comics more each time.
When you get to read, you have this insane sub list to read+life, also if your comic has a lot of chapters it'll take the reader more time to catch up.
So, I think this is common, you're not alone in this, nor the peeps that commented here, only massive popular comics match (and go beyond) their views with their subs.
This is only one hypothesis, also the correlation between subs and likes is another thing, but this is getting too long, maybe for another topic I'll cover it.
