We have an application. Besides most of its features, if user permits the application, everday it sends a tweet that gives information about user’s daily followers, friends numbers.
But in the last 10 days we had a very big decrease. I give general numbers For example:
In 25 September 2015 we sent 5800 tweets for 5800 users,
26 September: 5800 tweets for 5800 users
27 September: 5850
28 September: 5800
29 September: 5500
30 September: 5100
1 October: 4600
2 October: 4100
3 October: 3900
4 October: 3900
5 October: 3950
6 October: 3950
As you can see from numbers, starting of 29th September we had a big lose and we want to understand the cause.
When application tries to reach user’s data it gets 401 error. It seems like user revoked application access. But these users use website for months, for years, so it is not possible for all of them to revoke on the same days.
When I contacted some of users, they say that they didn’t revoke access. When they check their Applications section, they can’t see our application there. It seems like our application is deleted from some of users. I suppose these users are not frequent users. For example a daily visitor doesn’t have this problem, but a non frequent user (for example user visits website once in a 3 months affected from this.
Can you give any clue for the cause ?
Did we reach a limit or what can be the reason ?
