Most mobile operating systems allow you to set a preference for the text size on your device. It is often called "Dynamic Text".
On an iPhone: Go to Settings > Display & Brightness > Text Size.
On an Android: Go to Settings > Display > Font size and style.
Make sure that your font size is in the middle of the options. If you are using a default font size that is too large, you will see text overflow in display spaces that have a default width.
Here are some screenshots to help demonstrate this issue.
With a default font size too big, you will see text cut off in the display areas of the App such as the Map.
Here is another example of text overflow when viewing your Membership Card in the App:
Choose a default font size that is just below the middle size to ensure all of the text in the app displays properly.
Here are samples of the above Map and Membership Card when they are displaying correctly.
