Hi Mark
Thank you for putting some time into our issue.
I have located the matching APK from the domino server and installed it to one of the android devices that had the issue. While the layout is definitely different, the issue didn't occur. I get the feeling that when the "Show History" tick box was included in the app, this is when the issue likely started occurring.
While apparently the version we are using is supposed to be compatible with the current GooglePlay version, it seems it's not so we will now schedule an upgrade of the server and see if that resolves the issue for all users.
I will come back to this ticket when the upgrade has complete to confirm for anyone else who may require this information.
Thanks
Steven
