Did you try to access Discord from the Donna app in the English version? Or where is the Discord invitation that failed you?
Here is the invitation: https://discord.com/invite/KPdbfb8tet
I tried both in game and here, the link you send also didnt work for me. Screenshot attached (polish language discord)
Edit: It seems to be a problem with opera browser, using google chrome the invite worked like normal. Thank you for a blazing fast reply and help!
It happens often; in my case, I use a couple of browsers for different tasks or activities.
And I hope you enjoy the Donna club; I'm always around if you need anything °-°
