Weather Ball - Water, which was added to Primeape's moveset by mistake shortly after the latest Go Battle League moveset update, is about to be removed from the moveset of all existing Primeape that currently have it as a move.
Trainers, Primeape that know Weather Ball will have this attack updated to Ice Punch, or Close Combat if Ice Punch is already unlocked as a second Charged Attack. We'll also be granting 50,000 Stardust to affected Trainers for the inconvenience caused.— Niantic Support (@NianticHelp) January 27, 2021
For many players, this was a very expected move on Niantic's part. Weather Ball in any of its forms is not a move that Primeape is capable of learning in the main series, and this would not be the first time that a move along these lines has been removed from a Pokemon's existing moveset. While it's sad to see such a good move removed entirely, the 50,000 Stardust windfall should help to lessen the blow of the loss.
