My app’s URL: https://aperturomc-demo.glideapp.io.
My app creates a list of posts created by users. Each post is time-stamped, and they are sorted Z->A by timestamp. Old posts sort correctly, but when a user adds new posts, they are put at the bottom of the list, although they are then sorted correctly among themselves.
“Reverse list” works correctly, so I will use that going forward. For now, I am keeping the timestamp sort until you can look into it.
