Thanks for reporting, I will look for an existing issue and file if I can't find one, but just to clarify...
Is the text misaligned on the design surface as well or is it consistent with desktop 'preview' window?
Can you share info on the font and font attributes you are using?
So continuing to research but there has been a recent fix related to baseline position with mobile preview but it was specific to one font face I believe... Helvetica. So you should see the fix in the next public release.
If the font you are seeing issues with is something else entirely we will test locally once you provide further details.
