Most problems in ZeroTwo for iOS show a message that tells you what to try. Find yours below. If none fits, send a report from the app.
A chat will not open
When a chat cannot load, ZeroTwo shows a screen with a title that says why:
| Title | What to do |
|---|---|
| You are offline | Reconnect to the internet, then choose Try again. |
| We could not open this chat | The screen says your chat history is safe. Choose Try again. |
| Chat not found | The chat may have been deleted, or the link is no longer available. Choose Back to chats or New chat. |
| You do not have access to this chat | Ask the chat's owner for access, or go back to your chats. |
Back to chats and New chat appear on every one of these screens. Try again appears except for Chat not found and the access message.
A reply fails
A failed reply shows an error message in the chat with two buttons, Details and Retry. Choose Retry first. If it keeps failing, choose Details to see the error text, its code, and the provider and model. Copy full report copies all of it, which is useful to include when you contact support.
A message does not send
If ZeroTwo cannot accept a message, it says Message was not sent. Your draft has been restored. Your text and attachments come back to the message box, so you can send again without re-uploading.
When you edit, retry or delete a message, a dropped connection shows Network error. Please check your connection. Doing it while the chat is still answering tells you to wait for it to finish or stop it first.

Send a report
- Open Settings from the account menu in the sidebar and scroll to the About section.
- Choose Report bug. The form opens with the type set to Bug report. Send feedback opens the same form, and you can also pick Feedback, Feature Request or Help.
- Describe what happened, up to 2,000 characters, and choose Send.
The form sends the type and your message, so include the steps, the model you were using and any code from Details. For other ways to reach the team, see How do I contact ZeroTwo support?
