+Steps to execute
+
+- install and start th emailbox in the normal way and then allow the mailbox device to go to sleep
+- on waking up, there is no dialogue askign the user to swtich off the battery optimisation, because that was already done previously.
+- however, if we switch the battery optimisation on after installation and linking, and then we allow device to go to sleep, then on waking up... user should see the dialogue box asking them to switch off the battery optimisation?
