It looks like the issue that has forced Primeval Whirl to be “unavailable due to an extended downtime” has yet to be resolved. In a recent update, the downtime for the Animal Kingdom attraction has been extended through at least July 3, 2019.
As with the previous downtime announcement, this is no indication Primeval Whirl will reopen on July 4th. Guests with FastPasses for Primeval Whirl during the extended downtime should receive a replacement FastPass for an attraction of the same tier.
