I am submitting this bug here, because your bug report system is broken! I am using 2021.2.0b7.3246 I am trying to submit a 1.2GB texture array to my collab account. (I have the 25 gig package and have more than enough available room) It doesn't upload any of the file to the collab system and fails with a "Cannot submit change to server". Inside the log file it gives the following info: [Collab 2021-08-17 16:53:56 GMT][Error] 'Cannot submit change to server' (23) returned in 'C:\buildslave\unity\build\Editor\Src\Collab\Requests\UploadRequests.cpp' at line 149 [Collab 2021-08-17 16:53:56 GMT] UploadEntryRequest failed, Reason: 0 Url: https://storage.googleapis.com/unitycloud-collab-store-production-us/65edf09e-c715-4c28-8396-17c0cdaf7161/01dffd6c0a921975198fa12eabd35fc2?GoogleAccessIdemail@example.com&Expires=1629305635&Signature=XeAwXd4UCVIYSm3HYxIByTqVHvKdNd/QXuC+QNkhnQ++VenKMSA2vmQZhwZoUxNZCH2Aw/HsGf9Sv7fy7F+IElhOw0uH0EhCLOO/szW6DFLMe/yEIgG/edsZZ8eiMkryg3zIB8OiLw49BpzKy8UBYIyNK7pF3BtaKusP0qjoOHKsztwtJHF76gb51sjDcGjFMZbvT3eS/Vigx+LoKHuS/1+H4+MHuQOsNDm3ZDEySUs3h4rSMb4UxWMIWVWHUrvKo6zqGssKJc7KqIY10jhKPhNfbXsmon3qCgF5dwExuGnkiJJXGnxnkao7aWe/Z8ODJzmA3T1Bx0622lA6Euzw+A== Result: [Collab 2021-08-17 16:53:57 GMT][Error] 'Cannot submit change to server' (23) returned in 'C:\buildslave\unity\build\Editor\Src\Collab\Jobs\CollabPublishAsyncJob.cpp' at line 396 Appears that all 3 errors happen on the same publish attempt. I have tried deleting, renaming, restarting, upgrading. Nothing fixes it. ALL my other files are syncing properly. Its just this. So I'm guessing something to do with the size.
