[Bug] sort by upload date not functioning as intended

[acknologia]

---

Device information

• Tachiyomi version: ?
• Android phone & version: galaxy tab s7+ on android 10

Steps to reproduce

1. Use sort by update date

Expected behavior

Only newest updates from mangadex should populate list

Actual behavior

Half the list is random manga that is not the most recent updates other half is recent updates.

Other details

I am adding screen shots of the update date of the first 11 manga with available chapters. I also included what mangadex shows on their site. I have also refreshed each manga before screenshotting.

You should be comparing it to mangadex.org/updates/ not the front page. The front page isn't paginated. Also the app is not doing any sorting internally. It's just displaying what Dex provides in the order it provides

That makes sense but it's still not matching up for me. I recently switched over to android tablets and the app i use for my iPad matches manga for manga to the updates page. I did a few refreshed screenshots just now and neko doesn't match mangadex.org/updates/ either. 2 of the first 8 don't match.

1. A little background first if you have opened a manga at any point and have not cleared your database of non library manga then whatever info you see is being served from db and not the website. Just want to point that out in cause while this wouldnt effect sort order it could effect if something didnt show newer chapters when you clicked into it.

2. Are these screens in app when you first click the browse button, or after you apply a filter? If you applied a filter then its filtering based on /titles which doesnt not respect a users blocked languges, so you could be seeing updates from other languages in app

Closing this for now, once Dex starts updating again repopen if you have the issue
