1. MobileSheets explicitly has code to apply the transpose offset to the repeated chorus section, so I'm not sure why that's not working based on your description. I just tested this on my Android, Windows and iPad devices and it worked perfectly fine. If you go to Settings->About, what version are you running and is this with the Android, Windows, or iOS version?
2. Metadata isn't parsed if you just edit the file, however if you import the file, it should be read. The tempo field is certainly populated (I've tested this), but it won't overwrite an existing tempo when updating an existing song. So you have to have no value currently specified in the tempo field if you are updating an existing song.
3. {textsize} to revert isn't currently supported. There was another forum post about that. It's on my list for the next major update which is including a lot of chord pro features and fixes. {textcolor} is also not supported currently.
