TikTokOMatic – Cannot Authorize App – TT App Created & APPROVED!

I created the TikTok app as shown in your videos and i have been trying for a week to get it to work from wordpress to TikTok. The most i get when clicking authorize is my general login then it gives a redirect_uri error 1006. I have followed your videos and guides carefully so no idea what the issue is at this point. I seem to run into various issues with your plugins, but can work out most issues except for this one. I like the draft idea as I dont want to post all, just the ones i want to post so please help me get this to work. I have a live/approved app, i have a clone in a sandbox and have been trying various settings in the sandbox with no progress. Same error everytime.
