Is anybody there experiencing very slow mobile mining in last week?

Is anybody there experiencing very slow mobile mining in last week? At home we have three different smartphones whit different accounts, but for some reason mining getting very slow. Around 1 ETN per day on each device with 30 H/s. All three smartphones using different people with different registration emails and phone numbers. When I did KYC with Yoti app, on all three electroneum accounts I used same Yoti account to complete KYC. So now it seems like all three electroneum accounts have same person. Could it can be reason for slow mining?
