Just a heads up for anyone considering using Jira Next-Gen to manage your projects...simply don't bother.
I use a 2018 Macbook paired with a great internet connection and I can say after a year of using Jira Next-Gen that it legitimately is the slowest, worst performing web application that I have ever used.
There is lag with essentially everything action you take. Opening the board, opening the backlog, moving items up/down, reloading a page. Expect a massive lag and delay as well as choppy behaviour.
For a company like Atlassian to release a product like this is simple embarrassing. There's no excuse.
I'm currently wasting my time moving 5 projects back to the classic Jira mode because we are finding the next-gen unusable.
I've open support tickets, providing screen recordings, and have straight up been told that this is a known issue.
Reconsider your decision to use next-gen as you will likely switch back after a short while.
