Hi I'm having a similar issue to phroobin and rangerserena.
I'm attempting to change to a custom bot, but when I try to log in to the bot, it does nothing. The "SEND TEST MESSAGE" button is still grayed out. The only clickable buttons are "Connect custom bot account" and "Save". My commands work fine if the bot is StreamElements or my own username.
Apparently the feature can only be unlocked if I use SE.Live (I am), Connecting and midding SE bot (I did), and add the SE Tipping Link to a panel (I did, even though I don't use SE for tips, but it's there).
I've tried these troubleshooting steps <#helpdesk-selive message> and I can't get past step 4. Neither localhost:40404 nor 127.0.0.1.40404 work for me.
I have also attempted logging out/logging in, and checked for updates (none).
Please advise?
