If the pending rewards estimate in the top right corner unexpectedly shows 0 or shows a lower number than it did previously, it could be one of the following reasons:
A rewards distribution was just made, which would reduce your pending estimate
There is a glitch with the rewards tracker API
The pool(s) you're invested in stopped receiving rewards, so your pending estimate shows 0 after your last rewards distribution

As long as you confirm that you have deposited into a pool that is earning rewards, do not be concerned if your pending rewards show 0 unexpectedly.
To earn rewards, a pool must have three yellow stars by the APR (✨).
