The subscription renew automatically every 30 days, that happened in June, with 1.15 and had no problems. This is the first renew in 1.16. In the morning, I were unable to enter the realm, before paid. I waited to the account to pay automatically the subscription. After that, we were capable to log in and even played a few hours. I don't know what happened, but now it appears to be caducated no reason. Hope I can get a solution soon, refund or issue solved.
