[Q] VPN apps not working. Help pls!!! topic

Recently 2 months ago, I bought Micromax Android One. Last month I rooted it and installed Xposed.

From Xposed installer, I had installed an app named AutoVPNdialog which automatically confirms VPN request dialog.

Since then I'm unable to connect VPN apps.

Open VPN reads "VPN API permission dialog cancelled. Your image does not support the VPNService API, sorry :("

I'm not sure if the problem is caused by Xposed or BusyBox or something else.
Help me pls.....
