In the editor

ProblemWhat to do
The preview won't compileSend the console's first error to the assistant, or fix it in Code.
You can't click in the previewThe assistant is testing it: wait, or press Stop.
The turn stopped earlyIts edits are kept: ask it to continue, or Try again.
A file changed while you typed in CodeKeep mine or Use theirs.
Two chats changed the same linesA chat still working settles them itself; one that already ended keeps what is live, and its repair (or Settle these lines) asks you which to keep and uses credits. See Revisions and undo.
Edit in the preview waitsA chat is changing the app: edit when it finishes.
The bar says offline or updatingNothing is lost; drafts and messages send once it's back.
A panel shows a display errorTry this panel again, or Reload builder.
The Figma plugin refuses the codeA code works once, for 15 minutes: make a new one. If the plugin says it is out of date, download the current one and import its manifest again. See Build from a Figma design.

The stores

ProblemWhat to do
An Apple account is requiredAn owner or admin connects the App Store Connect key in Publish.
TestFlight refuses the uploadRaise an approved version (1.0.0 to 1.0.1), or build again for a used build number.
TestFlight stays on processingCheck status; answer any export compliance question in App Store Connect.
Apple refused the submissionDo what the step says (often a demo account, screenshots, or a price: choose Free in the form), then Try again.
Google's first upload failsUpload the AAB once in Play Console, then I uploaded.
Google refuses the upload over AD_IDAn SDK reads the advertising ID: answer Yes in Play Console › App content › Advertising ID, then Try again. An app without ads can block the permission and build again.
A Play release was saved, not sentA new app's first release waits for Send app for review in Play Console; with managed publishing, Send changes for review.
A build or store text says Saved in Play ConsoleFluxNative never sends uploads or store pages for review. Check Play Console › Publishing overview, then Send changes for review: Google sends every waiting change together.

Credits and keys

ProblemWhat to do
You're out of creditsThe agent pauses with its work kept. Add credits (Free buys credit packs too) or upgrade, then Continue in this chat. A first build that stops shows only the tabs it built; the rest wait in App as Planned.
