Discourse Hub app icon not showing as expected

We have two discourse instances (self hosted) and for some reason the icons aren’t showing as expected. In one, it shows the light-mode instead of dark-mode icon and in the other it doesn’t display any icon. From searching, it looks like this is dependent on the Large Icon (If left blank, logo_small will be used.)

  1. If there is not a Large icon, will it use logo_small?
  2. Does this need to be refreshed somehow or something to make it work? I have tried uploading icons multiple times without any luck

Thanks in advance!

In Team AnkiHub, I don’t currently have a large icon but I did previously. Currently the logo_small is there though (unable to upload photo because I’m a newer user)
