Thanks for reporting this! To enter road closures you do need to be a level 3 editor, which is why you were not able to.

There is a community of map editors sharing knowledge, tips, tricks, and best practices for really making the map work for wazers. You can follow this link https://discord.gg/sF39wStto join us on Discord. There are multiple channels available introduce yourself as a new editor, and you'll get plenty of help. After that one of the channels is "new_jersey" - this a great way to connect to our Area Managers, State Managers, Regional Coordinators and other editors. I hope to see you on our Discord server - it's the best place for all editors!
