Yes, I am. I’ve tried to configure your plugin according to instructions.
The Flickr has passed the configuration without any problem, but with the Google Photos, I was only succeeded to enter Google Client ID and Google Client Secret and then tried to get Refresh Token and wasn’t able to pass Authentication. More specific I wasn’t able to finish authentication – the Google has asked me about the account and then if I agree to allow my site to Manage photos and videos and when I click on allow I get the error.
