Pokemon Go Upload Management not working
On April 22, @NianticCasey-ING posted an announcement that upload management, including the ability to delay the submission of nominations, was live in Pokemon Go. He stated that an "Upload Later" button had been added to the nomination screen.
This feature is not present in my version of the game. I am running Android 0.205.1 on a Samsung Galaxy S9+ but a wide variety of players in this forum, including iPhone users also report that this live feature is not available to them.
