We are working on Dialogflow for a year now, and lately, we experienced some issues regarding stabilization, new behavior and new features causing problems. Among those problems is that when adding a synonym to an entity or a training phrases and hit save, wait for it to train then refresh again, all the newly added items are gone. It seems that Dialogflow is experiencing storage issues. And we are losing time trying to retrain again and add those items again and this is frustrating.
We have tried to troubleshoot this issue for more than a week and it seems that those issues still there:
Example 1: Synonyms already exist but Dialogflow treats them like they don't exist when visiting the "Validation" option.
Example 2: Adding new synonyms, saving and training; After a while, they disappear.
Example 3: The DF server is most of the time unavailable.
Please, Dialogflow Support Team helps us check those issues.
Thank you.
