First of all, thank you very much for adding support for Mastodon, it really is a wonderful thing! 🙂 As soon as I saw the option to configure it, I ran to try it, but I would say that something is missing.
That is, in the Mastodon app I have activated, in addition to what is active by default, as it says in the tutorial, I have activated:
I have made sure to copy the access token and correctly enter the URL of the Mastodon Instance (in my case https://mastodon.social/@NextNnet), but when I connect I receive this message: “Mastodon authentication response not understood” , and “Mastodon requires authentication. Update your settings to enable XPoster to send updates to Mastodon.”
Once Mastodon was connected to Xposter, I saw on the configuration screen that the “UserName” section is blank. Is it because of this? I get the feeling that some step is missing. Thank you so much!
