Ok so i did what u said, and i went to inprivate in microsoft edge, then i searched microsoft rewards there and as you can see, the stamp progress, daily streak, and daily set are not displaying. On my phone, i checked the bing app with the same account signed in, and i could see my streak, daily sets, etc. However, when i logged into the bing app on my phone and went to microsoft rewards, my daily streak was not increasing (from 58 to 59).
This has happened to me too.
If you don’t recall missing your streak today or yesterday, don't worry, you can actually ask the Microsoft Rewards team to help you restore your streak and report the problem.
Please use this specific link with the appropriate category: https://rewards.bing.com/support?categoryId=earning_points&subcategoryId=broken_streak
I really hope they can restore your lost streak soon. In the meantime, please continue using Rewards and completing your tasks as best as you can.
Goodluck!
