Using dremio community docker version with PDS MongoDB - it’s impossible to assign Reflection Refresh hourly values then the default 1h.  
Are the some advices?

@alex23ua If the reflection on the VDS, pick the PDS’s that it is built on and there you should be able to change the frequency of the refresh, see attached screenshot
