Miner offline for three days

Hello guys. My mobile miner is offline since sunday, 26/01/2020. When I open the app and press Start the mobile miner, is not working. I try to uninstall the app several times, I try to log out and log in but is not working. I opend two tickets on support but it seems no one wants to answer me so i ask here: Does anyone have any idea what that might be?
