staking really sucks for me. Last days I get 10 notification but only one is in the wallet. They disappear after some time.
I received over 500 blocks in 2 months and not 1 has disappeared. check the block explorer or your last transactions and see if the blocks are ignored
Ok so you get a lot orphans. Staking is also about broadcasting your information in time. This translates into having a good internet connection provides you with an advantage over someone with a bad connection. Do you have a good connection? And are you sure it is on a competitive level? I had a lot of orphans when my internet sucked.
