This item was originally removed from the November 2021 menu, replaced by the Allergy-Friendly Bacon Cheeseburger, then removed again in May 2022, replaced by the Allergy-Friendly Double Cheeseburger with Crinkle-Cut Fries.
Disney says
Two Angus Beef Patties, Smoked Cheddar, Lettuce, and Tomato, Pickle Slices, Grilled Onion and SJG Burger Sauce served on an Allergy-Friendly Bun with Crinkle-Cut Fries or Cuties® Mandarin Oranges 
Friendliest.app says
The Cheeseburger is free of gluten/wheat, fish, shellfish, peanuts and tree nuts.

Waffle-cut fries are fried in a dedicated fryer to reduce cross-contamination.

This meal contains milk (cheese), eggs (bun) and soy (cheese).

This meal can be made milk allergy-friendly by omitting the American Cheese or ordering as the
Allergy-Friendly Hamburger.

It can be made soy allergy-friendly by omitting the American Cheese and selecting Cuties instead of Waffle-cut Fries.

Note: The cheeseburger can be made egg-friendly by ordering on a standard bun, but introduces other allergens.

This item was removed from the allergy menu in November 2021 and replaced with the Bacon Cheeseburger, but can still be requested (without Bacon) and still appears in the mobile app.
