Hi Martin,
In our local env, we tried wrapping the shared apk, wrapping was successful, the sessions and events is visible in the admin console.
In case you are testing in Freemium env, we are having issues due to sudden load from few customers and it is under maintenance since last Thursday (02/04). When Freemium env is ready, we will report in CA MAA group in Yammer. Try again when Freemium is ready and let us know if you still observe any issues.
Also, request kindly to report issues in CA MAA group in Yammer as its actively monitored.
Thanks,
Godwin
