I received the email last week regarding the new The Stack System integration with the R10 for Speed Training. It came with the discount code to purchase The Stack speed trainer at a discount.
That would have been great news because earlier in the year The Stack system stated they were also now compatible with Android. So now have the opportunity to do speed training - NOT.
Did you forget to indicate in the email with The Stack System app announcement that it only works if you are iOS operating system? That would have been helpful before putting in the order for The Stack club. Really getting tired of companies ignoring proper Android integration when that's 70% of the World mobile userbase..
Also note that the R10, even if you have iOS is not yet compatible for The Stack app's full compliment of features like the new Wedging training program (to come later).
It is not exactly clear between Garmin and The Stack system websites that The Stack App, and R10 when using Android DOES NOT WORK (at this time).without some digging and back and forth with The Stack customer support. Although it took a couple days for them to get back to me about initial questions their customer service was great. Luckily they were able to cancel my order before shipping.
Currently with Android - the only way to use the Stack Club & The Stack App is by buying the Stack Radar as well as the Stack club.
