OK... Your screenshot looked nothing like what I see on my app!!! I managed to replicate it by altering the screen zoom on my phone. When I set my phone to be zoomed to the maximum value, yes... the serving measurement option disappears, and the 'Edit Custom Food' option is also rendered invisible. By playing with the zoom setting (it's in the Android display settings - or you can simply search for it within the settings app on your phone), the 'serving/measurement' does become visible and usable - when the zoom level has been reduced/set to 50%. It looks like, however, any option to amend the measurement setting is based upon the initial measurement that was set for the food in the first place (e.g. if anything was set with a weight unit, you can only change to a different weight unit... same as with any liquid measurement, you're only then given the options of setting a different volume unit)
Edit: Just played with the app on full zoom again...I can get the invisible units drop down to appear by tapping the screen in between the serving size number and the calorie value. Not always 100% of the time, though, even though the screen on my Galaxy S10 is quite large and there is a distinct gap between serving size and energy value. But if there's nothing visible for a user to tap on, why would they tap in a blank space? Edit end 🙂
This would appear to be an accessibility issue with the fitbit app on Android devices - any user who is visually impaired and has to set their device to be zoomed in (or, for those folks who feel that the default way in which apps are displayed is simply too small) are missing out on important functionality because the app doesn't look to respond to the zoom in the way that I feel it should. Users shouldn't have to adjust their display settings in order to use an app. then set it back to where it initially was so that they can comfortably navigate and use their phone
