Slippage issues with FXOpen

Since past 3 weeks I am seeing lot of slippage issues with the platform of FXopen. Many of my orders were not executed due to re-quotes issues. I seriously believe FXopen needs to spend some more time to develop their platform. Did any one faced this issue before.

Yes, I got same problem. Perhaps they are on upgrading/maintenance of their trading platform and server.

How often happens slippage?

I used to get slippage a lot with FxPro, so I switched brokers
