问题
I have developed a one page web tile using the online tool. The URL returns JSON from my own service. The first time the tile runs the data is correct on the band, after that though it never ever refreshes. I have looked into the forums and tried things out, including refreshing with the sync on the phone and ensuring the tile is closed. The headers on my service do not include Last-Modified or ETag as suggested in forums. Doing a post in the browser on my phone and desktop works like it should with the latest data.
My request headers look like this:
Connection: keep-alive Cache-Control: max-age=0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,/;q=0.8 Upgrade-Insecure-Requests: 1 User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.111 Safari/537.36 Accept-Encoding: gzip, deflate, sdch Accept-Language: en-GB,en-US;q=0.8,en;q=0.6
My response headers look like this:

Thanks for reporting this. We have identified the problem in the Simple tiles on Android and are working on a fix. We are targeting to have it in the next Android Health App refresh.

I can confirm for me using my Android phone and the latest version of MS Health (1.3.20213.1) and MS Band (2.0.4215.0 26 R), my web tile now works, so this was indeed a bug, nothing to do with my own web tile.
