I can't finish unity ads activation at unity dashboard!

[fkjaha_unity]

Hi! Now I’m trying to add unity ads into my project. But when I’m trying to press “Complete Activation” on unity dashboard, I chose that “No, I’m using Unity as my only ads provider. (No mediation)” and I get this issue “Unfortunately the ads provider could not be changed. Please try again.” What may I do wrong? And how can I finally complete this activation?

The same thing is happening to me.
Have you got it worked out in the end?

I normally use Chrome and I faced this error as well. I changed to Safari, logged in and was able to finish the activation. Hope it helps!
