I just connected to Express and didn't even realize FW 2.70 downloaded. According to the list, there are several things to test out. I just hope this isn't like the initial release of the FR 235 where one thing was fixed, but the updated crashed something else.
Update: I can now add and change test responses. My Garmin speed & cadence sensors still won't sync unless I pedal my bike and hold the watch inches away from the sensors, so no help there. The other fixes listed I didn't have a problem with or wasn't aware there were issues. So, it appears 2.70 allows me to change text messages and that's about it for me.
