How you resolved it ?

[deimantasa]

Hi @FirdousNath , we've decided to drop amplify due to too many issues at that point. But I heard now it should be much more stable. As when we had a chance to play with it, it was still in very early stage of development.

Hey @deimantasa we're sorry to hear that. We had our GA release last Monday so the current version is much more stable.

@FirdousNath could you explain your issue in a separate Git issue so we can help you?

[deimantasa]

@fjnoyp , no worries mate! Nothing can be perfect. Especially at that early stage. I was happy to read that recently you guys released much higher and more stable version. Keep up great work!
