Why is there no way to select the language all across the app? When I change the Sim card in my phone, the app switches to the Sim country language. I went to the Middle East, the app switches to English (Ok), Then I came to France them Italy, then Germany and the app would switch language for the stories, etc... I found no way to select and keep a particular language. It needs shortcuts between My Watch and My Page to go to the other pages of the app without having to revert to the home page.

Slow and very hard to set up. Unacceptable privacy policies. The open source Casio G-Shock Smart Sync app has all of the same functions and no privacy issues. There is absolutely no reason why Casio would need to have your e-mail address, date of birth(!), and permission to store all of your usage data (including location history and alerts). Given that the open source app doesn't need any of this (and is smaller and faster), it's clear that the data processing is excessive.

The app works good, it's nice and easy to connect (bluetooth) watches and access the settings via the app. Marking G shocks as favorites is also very nice, I think being able to buy them via the app would make it even better. I was hoping that this app would also have other Casio watches like the Vintage and Edifice lines in them. This would be a nice addition
