How does LLM-assisted localization handle App Store character limits?▼

LLM-assisted localization handles App Store character limits by applying strict, per-field character-limit enforcement during the translation of description, keywords, and promotional text before uploading.

What is the best way to localize App Store keywords for different regions?▼

The best way to localize App Store keywords is using LLM-guided translation with locale-specific keyword strategies, ensuring translated terms meet Apple's strict character limits for each target region.

Do I need asc authentication to prepare .strings files for App Store localization?▼

Yes, asc authentication is required to resolve app, version, and app-info IDs, download existing metadata, and verify successful field-level uploads after preparing your .strings files.

Why does App Store Connect localization fail when updating version metadata?▼
