Hi everyone,
Did you notice a drop in the volume of tweets when using statuses/filter ?
We’ve had a dramatic drop in the volume we’re receiving.
This is what we’re using :
https://developer.twitter.com/en/docs/tweets/filter-realtime/api-reference/post-statuses-filter.html
Also, userids are now sending 401 responses.
We can’t explain on our side as we didn’t change anything that could affect this, and the keywords we’re monitoring didn’t drop in volumes this much.
Any help would be appreciated 
Mehdi.
