Mobile app doesn't sync

I have an app that uses evens and a calendar.
For each event on the calendar, I added an emoji for the title. For example - if the event name is “work” so at the calendar I will see “work+emoji”.

However, for some reason, when I check the calendar via the Glide website (from the editor tool) I see the name + emoji. But when I check the app via mobile (or via the computer, as a test) I don’t see the emojis.

Any idea why?

Which emoji are you using? Not all emoji are compatible with all devices. Some newer emoji may not be available on older devices.

Do you have automatically publishing turned on?
Have you refreshed the browser so the that the latest app changes downloaded?
