This issue is still critical.
I can never know when new Canvas IDs are collected or old changed.
Which is basically the same like not using BAS at all.
@selenagomez2391 I tried authorizing on 2 IPs and got the result that:
On each IP, I can get 100 fingerprints every 3 minutes.
So, IP authorization cannot reach 1000 requests every 3 minutes.
It never happened before.
