Hello canyoncf60,
I’m experiencing the same problem with the query editor as it is also missing in my grafana’s 7.4 installation. It happens in both Firefox and Chrome. It allows me to write code query but no chance with the query editor.
Just a stab in the dark here, but I noticed that you’re using the Flux query language (not InfluxQL). Meanwhile, the screenshots you show, and the discussion in the thread appear to be about the InfluxQL query builder. That won’t be available for a Flux datasource.
