In recent days, I have noticed some understanding problem in my bot. Without any change, some intents no longer respond correctly. Even intent with buttons and the exact phrase in a follow intent. Seems like the comprehension ability has been altered in general. Here is an example which has always worked and which has not worked for a few days.
Button: I am a tenant
: I am not a tenant.
In the intention "I am a tenant" I had this in training sentence:
I am a tenant or his legal representative
I have removed the "legal representative" and it works. What worries me is that it has always worked.
Has anyone else spotted any issues these days?
