Yes, you can keep using the old version. We are keeping the Version 2 alive as long as people keep using it:http://v2.jotform.com
Can you identify what in the new version is consuming your time? Is it because everything is new and difficult to find things? Is it because it is slower than before? Do you see some bugs?
We optimized the old version for 3 years. So, there is doubt that it is better than the new version regarding stability and speed but I hope that we can also the same for the new version because it has a greater potential. Thanks for your feedback.
