WebUpdate and CT-Version

(1) I have installed the past CT version 3.514 and WebUpdate works fine.

(2) Than I install the current CT version 3.515, publish DEF and ZIP-File again, load it in Web again. When I push “Check for Updates” in Android-CT-APP nothing is happened.

(3) When I install the project again by using Android-CT-APP → webinstallation and put again the url, than the updated project will be installed again. On smartphone I have now 2 parallel projects with same name. The old I have to delete by hand.

(4) Every further change in this project works with “Check for Updates” as expected. (like in 1)

=> Could it be that a CT version update on PC and the “Check for Updates” is not automatically possible?
