**Steps to replicate the issue** (include links if applicable):
* Save articles
* Sort by "**recently** added"
* The correct default is new > old
* Log in from app
* Enable sync
* Add article from desktop using the [[ https://www.mediawiki.org/wiki/Wikimedia_Apps/Synced_Reading_Lists | official browser extension ]] (may not be needed to reproduce bug, I'm not sure)
* List order now is incorrect (old > new), even if signed out
Also:
* Disable sync and sign out
* Add article
* It goes to the top as expected, but the rest is reversed, so it becomes:
* new
* **old**
* **new**
(In bold are the permanently reversed articles that were saved before the sync.)
**What happens?**:
Signing in on app and syncing reverses saved list order for good
**What should have happened instead?**:
Order should not have been affected. (New stuff being buried way down is not ideal.)
**Software version** (skip for WMF-hosted wikis like Wikipedia):
6.9.4
(Appreciate all your efforts.)
