File size sharing via email in Lightroom mobile App

Hello,

I have been using the Lightroom mobile app to share via e-mail for almost a year.  I use a full frame high pixel camera so the Raw files are fairly large.  The app did a good job of converting theses to jpegs and giving me a choice of files sizes to send.  Up until the last update the choices of  jpeg were approximately 10 megabytes to 3 MG,  now they are much smaller.  Does anyone know of a setting I can change to get back to the larger file sizes?

Thanks in advance, 

Dave
