Yesterday in the evening no troubles at all, and hope it will be the same today. I will report here.

Possibly there has been a bit of a disconnect between the servers and your quarantines/ trade centres and you/the game has tried to transfer too many animals into the trade centre and it is attempting to process a backlog.

I had this during a bad bout of the glitch where newborn animals are shunted into the trade centre when leaving the game - a whole bunch of baby chickens and wolf cubs overflowed my trade centre and I had to manually send them back out to habitats and see it refill a couple of times before I had control back (so many chickens).

Wow. I never thought about how many baby animals were in the trade center. I think some of the animals WERE baby chickens I never put in it.

The sandbox zoo, with only 3 animals in the trade center, is working fine, while both franchise zoos are having this glitch.

No, absolutely no issues today in several franchise zoos. There are different servers, I guess?

I've done everything grampers62 suggested, but haven't tried playing again yet. Will try now.

I still can't trade/quick trade anything. Only release the ones that can be released.

Is anyone else unable to play Franchise Mode due to maintenance?

They do maintenance on the server, usually weekly. The game will be back up shortly when players see this.

Hopefully our last convo gets you straighten out.
For other players, It seems the op closed a zoo with a lot of animals and the game saved them all in the trade storage but there were more than the user interface can display. It will just take time to get the trade emptied down to below 200 actual saved animals so the the anti-cheat will unlock the op's trade center for public trading.
I have seen this happen a couple times and it is quite confusing and complicated when it happens due to the player getting no info on what is happening. Seems like a bug but then again, It;s good that the player doesn't lose a bunch of animals! Perhaps there should be a notification the trade is overfilled... Should probably post this over in the official forums.
