Wyze App and Scale History

I went into the SCALE part of the Wyze App… Got into HISTORY and there didn’t seem to be ANY WAY to get back (iPhone version) to the main scale or home screen!
I ended up Closing the app and reopening. Anyone else know the trick to get back?

There is a back arrow in the upper left hand corner. I’ve had problems with the display on my Iphone (7+) correctly displaying it consistently. Shows fine on Ipad.

I will look again thanks. I have a iPhone SE and the extremes of the display are sometimes hard to get to react.
