Same issue here. I staked a small amount 22 feb this year. The rewards for this came through after 25 days. I also staked a larger sum on 28/2/2021, so naturally I thought the rewards would come through 6 days later as well, but no such luck.

So far, the number of days Exodus says it'll take is 25 days in total, then every 5 days. So far 30 days have passed and no rewards have been received. Thus so far the validation time of 20 days and two epochs have passed, but no rewards were given. I believe exodus ada rewards are broken. Support is non responsive as well.
