Thank you for your report.

I think this is due to the meta refresh issue (https://github.com/vesoft-inc/nebula/blob/master/docs/manual-CN/get-started.md see the bottom part)

By default, it takes about 2min to refresh meta change. ( Of cause, this is a bad choice for the beginners)

Can you try in the console:

 get variables graph:load_data_interval_secs
