Firstly, I have a 2.2Gb file saved as a .PSB that was able to be edited and saved fine before the move to 2021. Now I open it and I can't merge layers, save, or anything. PSDs are still fine but not PSBs. Any ideas?
And secondly, I really need to sort this and have gone to the help page, but every single link I click just takes me back to the help page. Where has the chat box gone? I just go round in circles...
