Relevant info: comic has 69k subs, updates daily (so no weird spikes and drops due to that), is mature so it is hidden on the app, it is currently promoted in the vampire feature section so I imagine it could have been even worse without it. My patreon growth came to a standstill around the same time the site updated. By standstill I mean no new patrons, which for a big creator translates to "losses are not compensated". Usually you expect losses to be compansated plus a bit extra meaning a slow growth, but around the site update i saw only lost patrons without new ones to make up for it, and the subs on the lowest day were barely enough to equate what I assume I lost in subs (yeah when you have big numbers it also means big daily unsubs).
I don't want to complain too much because I know tapas is working hard to fix it and I really love this site, but that one standstill day on patreon really scared me. I'm trying my hardest to keep my company growing until they get it fixed but I really do hope the algorithm and general site setup is something they're planning to fix because right now mature comics that aren't trending are vanishing into the void.
(My patreon has begun to recover, just thought I'd mention because I don't want anyone to pity me, all I wanted was to provide relevant information)
