I published my PVA to MS Teams a while ago as a bot. It worked perfectly.
A few days ago it stopped working.
It works perfectly from a web test page and from the 'Test your bot' option, but it does not work from MS Teams.
It is as if it wouldn't recognise phrases that are used in the bot for branching.
It's response for any phrase is:
Sorry, I am not able to find a related topic. Can you rephrase and try again?
As mentioned, the test app works just fine, it only happens from MS Teams.
