Here are some of the most common issues that our users are running into:

Live Test

Issue: You see a blank / white screen when you live test (even if there are items in your app)

• If you have a Navigator as the first item in your tree, make sure your screen is dropped within it

• You have unconnected blocks

• You have an event triggered by a Screen.Start which may be causing the screen to crash

• Your app and desktop may not be logged into the same account

Issue: Image is not showing up on your phone

• The height or width of the image may be set to 'Fit contents'

Issue: Trouble downloading AAB and APK files from Google Chrome

• The Google Chrome browser blocks downloads for your safety. If you open the email with a download link for your APK or AAB file in Google Chrome, you may not be able to download your file. You can try one of these options:

  1. Open the email in another browser, like Firefox or Safari, and download the file.

  2. Change your Google Chrome settings to allow you to download files. Please note that changing your browser security settings can make you more vulnerable as you use the web, and Google Chrome does not recommend disabling this setting.

• It was a Testing Download and has expired after 72 hours.

• It was a Distribution Download and you switched to the Free plan.

• It was a Distribution Download and your App (Bundle) ID doesn't match your Active Bundle ID. You may need to enable it in your Account Settings before the app can be used.

Thunkable is free to use to create public projects.

We offer paid plans for individuals and businesses looking for extra features to meet their needs. .

Public projects are included in the Thunkable Public Gallery for anyone to preview and remix. Private projects are not included in the Thunkable Gallery and are for your eyes only.

Private projects can only be shared with other Builder users. Please note: If you share your project with another Builder user, they have the ability to make the project public.

Thunkable projects are saved automatically. If you wish to create a snapshot of your app at a certain point in time, you can save a version of it. More information is available here: .
