I am using - Aegeus version v2.0.4.0-4b52efe So I think it is the latest version of wallet. Installed 22.sept. and after that, receive only one-time staking rewards.
Also think that you are both using the latest wallet version. The only thing that confuses me is that you only received 1 reward in the past days. Based on the stats that I got from Masternode.Online, you should be receiving rewards every 1d 7h (more or less). So, both of you should have received few more rewards than that. I don't know what could be the problem for it. Well, sometimes, those data from masternode monitoring sites are inaccurate.
