1. I think you cannot see the current streak at the moment when you will complete a lesson you will get a popup that you have completed and you'll get the streak number is ....
2. I started the lessons from 2:00Pm yesterday and I completed the second streak on 12:00AM[I thought that the time duration was 24 hours but I can complete the second lesson before 24 hrs]
if you do not continue your streak within 24 hours you will lose your current Streak and then next day you have to again start with the first streak.
3. You will easily get that information in the FAQ.I think you can but let's read the FAQ once. If you miss a day, you can rejoin the streak, provided that there is enough time for you to complete the streak in 15 days.
If you do not complete the streak, you will not receive any of the awards.
I will urge you that email to sololearn at [email protected]
asking then what to do and also ask whether if losing the streak would allow to start a new0
