Created app A, got to version 6 - made a mistake and removed it from the store.
Created a new Beta app B with new name and UUID, and now version 7
On the download page of app B which shows all the correct names and versions clicked Download but every time app A still installs.
This might help solve why the latest app updates to IQ Store are not installed, only previous versions.
