My applications produced after March 30, 2020 do not work. I am waiting for an urgent solution. what I mean was I install it on my phone after my application is produced and sent to me from you, but unfortunately it does not work. The problem is continuous still. So, I am downloading and loading the app to my smart phone. But I am logging into the application after the installation is finished, but can not logging in. It throws out me. Do you understood me. Please could you solve the this problem urgently.
