top section on mobile view scrolls/jumps down automatically on site load (7.1)

Hey everyone! It's my first time posting here. You all have been an invaluable resource to me already, so thank you!

My issue:

Note: This is happening on mobile view only (as far as I know), and only when viewing on an actual mobile device. I'm viewing on an iPhone 7, for reference.

The site is currently password protected. After I enter the password and the site loads, the top section jumps down a little ways (enough to where you can see the next section). If I tap the logo to reload Home, everything looks the way it should.

I had previously tweaked the padding and size of the mobile menu, though after a lot of testing, I don't think this is the culprit. But maybe it is!

I was able to brute force a solution by changing the min-height of the top section (on mobile only) to 110vh. But this is not ideal, because if a user goes back Home, they will see the text and button in the top section appears a little lower than when the site originally loaded. 

This is kind of nit-picky, but my site is promoting my web design and content creation skills, so you know, wanna put my best foot forward and all that!

Thanks in advance for your help!
