I have qualified ugc net in December 2019 under ews category. But I got my ews certificate after publication of nta net result. is there any problem in this matter?
Well I don't think so that you will be getting any problem as long as you have the appropriate documentation. Although you can mention it to the authorities that your documents were under progress when you applied and got it ove it was approved. So I think you are good to go.
I hope my answer helps.
All the best.
