Actually, you can switch on and off as much as you want as long as you:
1 - go a total of 10k or more.
2 - earn two candies.
Normally, condition 2 means you have to walk two 5k segments, but that requires more bookkeeping. Easiest to go 10k in one go. Also:
3 - Eevee must be your buddy when you evolve.
If you do all three, then you get an Espeon if it's daytime where you are, Umbreon if it's nighttime, and a random gen1 if the game can't identify the time of day because of a bad GPS signal.
Probably some of the common mistakes mentioned above.
It's not just walk 10 km, but also earn 2 candy. You can walk 6km and swap to another buddy, then swap again and complete the 10km but missed the second candy.
Night means night in game, not in real life. They may not match.
It must be evolved while it's still your buddy.
If you lost GPS signal for a couple seconds while you pressed evolve button, fail (impossible to avoid this if you are unlucky with your fingers timing...).
