Thanks for reporting this issue to the Community! I definitely agree that this situation is odd. If it's working on your Chrome browser, it should also be working on Safari and via your iPhone app as well!
For your Safari browser, can you kindly try clearing your cache and opening a new browser and retest? You may also want to use Incognito mode for the testing.
Regarding your iPhone app issue, please try uninstalling and then reinstalling the app to see if this helps.
