Bustacap: workaround until they fix it:

- log in to PSN (store.playstation.com) through your browser

- after the login open this link: https://ca.account.sony.com/api/v1/ssocookie
Copy content of "npsso"

- open windows explorer and enter the following into the address bar at the top and press enter
%LocalAppData%\GOG.com\Galaxy\plugins\installed\

- open the psn_{random number} folder and edit the plugin.py file with your favourite text editor

- go to line 64 and change it from:
stored_npsso = stored_credentials.get("npsso") if stored_credentials else None

to:
stored_npsso = "Copied value of npsso"
("copied value of npsso" should be a 64 character long text consisting of numbers, lower case letters and upper case letters)
(the quotation marks " " are important!)

- restart GOG Galaxy
- try connecting with PSN again

Phantom68: @Bustacap Sorry, to clarify the CAPTCHA appeared when I was not aware of the workaround. You are correct in saying that the CAPTCHA does not appear after the workaround.

Sorry to be a pain bit when you claim the PSN page on GOG GALAXY are you talking about the got app?
I can see on the left-hand side a list of all platforms bookmark

TheRealTonyStank: I'm probably missing something here, but I've done Bustacap's method and it worked, the only issue is that I can't figure out how to claim the GOG Version. There's no banner or notification. Just my synced PS4 Complete edition, along with other ps4 games. Why can't I claim it?
