I have this too again now. I fixed it 2 times already with code given to me by GP, but now it’s happened for the 3rd time, and I have to look into fixing this again. Please make this consistent, the way to fix it, not changing it up all the time so I have to re-fix it every time.
Here’s my forum topic on how to fix this from only 2 months ago: https://generatepress.com/forums/topic/tiny-logo-on-mobile/
I’m looking for a solution on this again now as that solution has stopped working. And previous to that, the code I used before that to have a properly sized mobile logo stopped working too.
