I used Quickapp Ninja free app builder a long time ago, before finding out they are scammers and I stopped making their apps, but too late, after uploading like 10 of their apps to my google play account, before I discovered Buildbox. In 2016 I had no idea about apps, so I said let me try this website free app builder without coding. But right now google sent me violations, and that I need to update these apps. I contacted Quickapp ninja that they need to fix these violations, but they are not replying at all, it's been 2 weeks like this, many developers have lost their google developer accounts because of them. I was thinking that I can make my own apps, use same keystore that these scammed apps are signed with, and I replace these apps with my own, but google sent me back a message and told me if you are enrolled in the app signing key then yes we can help you. But the disaster is I never enrolled in that program, so I think my account will be suspended soon I have 4 rejected updates and 1 removed app right now.
