mpg not showing
 

for some reason I cant get my mpg to show up for the past 2 fill ups.. numbers 7 and 8 on my list... can someone help me out?
Thanks

I have the same problem with my last fuel-up. The one before was a partial but this one was full so it should show mpg but no dice. And yes the last two entries are marked correctly.
My entries so far
1 - first fillup recorded - no mpg shown of course
2 - second fillup recorded and mpg is reported correctly
3 - partial fillup and no mpg shown which makes sense
4 - full fillup recorded but no mpg shown as it should be

Also, the desktop interface is reporting the same thing as the iOS app.

Ah, this is normal behavior for some reason, but I don't quite get why, as you can combine a partial with the next full fillup to get mpg numbers:

But not a bug in my case.
