If you have missing deposits on Poswallet try to refresh the block now. They found a bug in the refresh feature. I managed to get my two missing deposits from a couple of weeks ago today!
I will login now and give it a try as I'm missing some 808 coins from transferring them over from the exchange to the staking wallet last week and they never showed up so I'll give it a try as I did refresh the block a few days ago and nothing happened so hopefully now it will work and I'll be sure to report back here.
