As an Admin, you have the possibility to access designs, create a sub design and change the logo.
Click on System --> Designs --> Click on the three dots by the name of the already existing design --> Add Sub-design --> Give a name and click on Save.
Change the logo
If you need to change the logo for a certain design then go to your System --> Designs --> On the right side of your screen there is Logo --> Click on Upload under Header Logo to import a new logo in the header --> Click on Upload under Cover Page Logo to import the new logo of your cover page.
Note: We encourage you to resize your logos before importing them. The recommended size for a header is 250x64px.
