Twentig Footer Options don’t work

Hi,

I am using the Twenty Twenty One theme and the Twentig Plug-in.

I have various issues with/questions regarding the footer options:
1. the site logo doesn’t show in the footer (it is checked in the Twentig options and it shows in the header)
2. the credit doesn’t show (neither default nor custom)
3. “Inline” or “stack” don’t seem to make a difference?
4. can’t change the colour/appearance of the social media logo (e.g. remove the blue circle around the Linkedin logo)
5. I would like to add blocks to specific columns (so they are approx. of the same height, e.g. put the credit and the social media logos in one column). Is there a way to do that?
6. Is there an option to display the content in rows rather than in columns?

Many thanks in advance for your help.
Best regards,
Andrea
