We've been running some interactive email tests, and none of our content is displaying in the default email app on a Samsung S6 (Android v6.0.1) - we've built a few interactive emails previosuly, and this is the first time we've come across the issue.

We have fallback content in place, which is being displayed by any email clients that don't support the interactive content, but at present neither the interactive content or the fallback is being displayed on the S6.

Just wondering if anyone has come across this problem previously, and if there's a solution?
