  1. Close the app fully and reopen it.
  2. Check your internet connection.

  2. You can also make changes directly in the FastParty app if it’s quicker.

Tell Antsy what to fix in the same conversation:
“Change the event name to ‘Summer BBQ’ and move the date to August 3rd.”
Antsy will make the corrections immediately. You can also edit the event directly from the event settings page.
