How can I find out when my Series expires?

The Series expiry date is found in the 'congratulations message' which is shown when a Series is mastered

▶️ Tap My Learning and then Mastered, Select the Series from the list. Then swipe down to show the previous chat history, the last chat message shows when the Series will expire.

⚠️ Once the Series has expired it will no longer be listed in the App, contact your Manager to be enrolled in the same Series again
