E-Tube Project Cyclist and Android 15

Shimano released a statement regarding the latest version of the E-Tube Project Cyclist mobile app and Android 15:

To our valued customers

Thank you for choosing SHIMANO mobile app. It has been confirmed that the app does not work properly after updating the OS version to "Android 15" offered by Google LLC. We are currently working on the compatibility with the new OS. We apologize for the inconvenience. Please refrain from updating your OS to Android 15. This issue will be fixed in an updated version of E-TUBE PROJECT Cyclist that will be released in the near future. Once fixed, the information will be posted on Google Play. Please check back again.

We appreciate your patience.

Personally, I haven't had any issues using Android and e-tube project, but it's something to be aware of.

UPDATE: A new E-Tube Project version was released, and it can now be used with Android without problems.
