Still using Startapp? Ecpm dropped!

Startapp ecpm suffered a huge drop recently.
Anyone has any idea what is happening?
Will Startapp ecpm be back to normal?
Is it worth staying with Startapp or proceed to try out other new ad networks?
Thanks.

same with me, but i want to keep using startApp till a few week to track

StartApp rates are not stable, they fluctuate a lot. There’re better options out there now, better switch to other network.

Same here. I have some apps with 0 ecpm. I opened a ticket with support but nothing yet.
