Yes…And it is not you…it is Amazon…They sometimes have big delays in saving. There are some things you can do. First, if you are using IE, switch to Chrome (if you have it) or any other browser. That sometimes works. If you have browser with ‘privacy mode’ use that to access the site, or simply clear the cache and cookies on the browser you are using. Also, to be clear, are you saving the slots, or the whole page? Sometimes it is a good idea to paste the intents, create the slots, and then copy the utterances and then press Save at the very end.
Again, you should get good results if you change up browsers or clear you cache/cookies.
Let me know if that helps. I am not having any issues right now with it, but that doesn’t mean it is load balanced in another area and the server you are on is having issues.
