Went to the new app and noticed that when I choose oldest birth for the listing options it wasn’t.
I am also experiencing this problem. I will tag @eaglereptiles to see if he has any ideas. But I recommend powering down your phone and turning it back on. This has fixed problems for me with the app.
Maybe depending on the memberships some animals are listed higher than others overriding the filter?
The link shows:
sort=old, so the actual filter IS working… its just not doing it’s job right. Rather than sorting by year it is sorting by month.
This seems to be a case with the website as well and not the app specifically.
Like the Sort by “least genes” in US region bug this seems to also be a US Region issue… I’ll bring it up with the team
