Hi @knjigor
We still have to find a good way to integrate the new plugin, but… You can take the .tar.gz from here: Release ojs-3_0_1-0 · pkp/quickSubmit · GitHub. You will have to remove the current quickSubmit folder in your plugins/importexport/ folder, to extract the package there and rename the new folder to “quickSubmit” instead of (quickSubmit-ojs-3_0_1-0). I checked it right now with the current ojs-stable-3_0_1 branch and it worked for me. How did you try to do it i.e. does this way work for you?
Best
