It looks to me like you figured out your problem. I am checking here because I believe I may have a similar problem.
Last week, for no reason I can figure out, my mobile flyout menu stopped using the correct link color. This is still set as correct (black links/white background) but it is not showing as such. Instead the mobile links are present, but you cannot see them because they are white on white.
I was hoping that was your issue also but I am not sure now because when checking I see on my phone that your flyout is working fine now and it has navy background with white text, whereas your main site has white background.
My question to you @katem70 … how did you modify the flyout background separately?
Or if anyone else might have suggestions as to how to figure out and/or trick my problem into working.
