I was trying to create an example TempoStack instance using the web console and I think that there is a bug in the form that makes it imposible to create it with multitenancy enabled. I never use the web form, but I was actually curious of the default configuration when having it enabled. So the error is the following:

Danger alert:Error
Fix the following errors:
Error "Invalid value: "route": Ingress cannot be enabled if jaegerQuery is disabled" for field "spec.template.queryFrontend.jaegerQuery.ingress.type".

The issue here is that I already disabled the Jaeger Query UI, but the form only allows Type: Route or Ingress.
