Nice to meet you too @arcadesind, I'm working as the backend engineer of Cocoon. I cannot really help with Cordova related problems but I do my best to keep Cocoon as stable as possible knowing that this is a fast changing environment.
I'm not the admin, I just keep an eye over the forums to detect if there is any problem with the platform but I do certainly answer the PM's if there is any doubt .
@shubhamrathi9, I'm sorry, if there was an easy fix we would have deployed it but there are no workarounds, we have to update libPNG in canvas+ and upload the new version to the testing environment before releasing it.
Sorry again for this inconvenience and thank you all for reporting this issue, best,
