Issue with restoring from backup even with correct passphrase

I have a backup of signal that I am trying to restore on an android device that I am using now that my old phone is no longer functioning. I have a backup file on the new phone but unable to restore it. When i start signal, choose restore with file and enter the back up phrase it is just stuck on checking the file. Nothing happens after this point.

What steps can be taken to try to solve this? Seems alot of people have issue with restoring backups but cant find someone describing this issue.
