From the main page of this JIRA:

"This is not for help or support, please see this helpful article if you need help with Minecraft."

**That "helpful article" points users back here for technical support, putting users into an infinite loop, and ultimately no way of getting support from Mojang on the product. In addition to fixing the completely broken 1.14 release, you might consider fixing your support process, and provide your paying customers some level of support.
