Issue fixed. I had opened up a new one and the issue was with the export settings. For others who might run into this issue. Make sure the XPUB is on over Android (which is what I had.)

It opened and loaded just fine.

Since the update the pubcoder file has not been able to export via wirelessly or APK to my android device.
It will tell me that I need to get a correct QR code when the one generated is fresh from the program, or when the downloaded APK is installed it'll just crash and kick it out. I've looked at the size of the file and it isn't too terribly heavy but it is hefty at this point as well. (3.9MB)
Is the app getting to large to support, or is there another issue?

When porting the app through Apple Market to iPhoneX the app scales to far and cuts off parts of the app.
This makes the app scroll left and right and makes menus unable to be used.
Is there a way to fix this?

While scrolling on a samsung galaxy tab S the entire screen begins to shake up and down. Sometimes this will last for a few seconds-- lasting until we change the page it's on. Is this an error on our settings or is it a glitch with the program?

Has anything been found out about the transfer issue?

When I export from InDesign to EPUB it shows the underlines correctly.

I tried opening a new project importing the file directly and then I exported as an EPUB, and still there were no underlines. So I guess that's an issue with InDesign?

When I bring the text I've edited in InDesign, it keeps 90% of the style; however, I lose all underlining I've done. I've tried to use different ways to underline in ID to see if it was something on my end. Though no matter how I go about underlining the format does not stick.
Is there a way I can get this to work?

UPDATE:
Error was found, the project icon was not 1024x1024 and the app store would kick out the PUBcoder icon.

How would I go about changing the App Store Icon to the one we've set up? Is it in xCode?
