I lost my streak yesterday even though I'm pretty sure I had streak freeze activated, is there any way to double check if my loss was legitimate? Or does it not work if you're inactive for more than 24 hours?
The Streak Freeze only works once for one day missed. If you miss another day before obtaining a new streak freeze you will loose your streak.
But that's not what happened. I did my lessons Friday afternoon, was inactive all day Saturday, and woke up this morning (Sunday) with no streak. I have had the streak freeze save me once before and I'm 98% sure that I bought a new one immediately afterwards.
Are you certain that it did not pass a few hours (maybe one or two hours...)...I used it a couple of times and had no problems at all...altough I see a lot of similar discussions here about that...
