Hi @Novicki, Joseph,
Thanks for your information.
Did you try to change the logo.png file in MDS 2019?
For your new logo image (please rename your file to logo.png), try to get the same dimensions as the original image on the server and if refresh the browser page does not bring up the correct logo, you can try restarting the site in IIS.
Please feel free to share your issue here if you have any confused. We are looking forward to hearing from you to assist further.
Regards,
Lucy Chen
