AppMySite

I bought your AppSumo Tier 1 plan on 29 November 2023. I built a test app at that time on your platform and there was no such line on the top of the app stating "this app is built on Appmysite" but now it is there. will it stay there, when I publish my app on google store. If yes then you should have done this at the time of purchase in december at that time there was clean interface. Now we can't do anything we can't get our money back.
