Android App Links fail silently when the certificate fingerprint does not match. Here is the real keytool output, the upload key versus app signing key trap, and a small checker you can run before you deploy.
My Second App From the Same Codebase Ships With a Distinct-Value Manifest
Google Play has drawn a clearer line around low-value apps. Here is how I decide where the distinct value of a sibling app lives, and the small script I run before every submission to check that the two apps have actually diverged.
Leave image out of eas.json and an SDK bump moves your Xcode and pnpm too
If eas.json has no image field, your builds run on the auto alias. Move one SDK alias and Xcode, Node.js, pnpm and fastlane all change together. Here is how to read the image name out of your last green build and decide whether to pin it before Xcode 27 lands.
I counted how many versions expo install starts recommending after one patch bump
What expo install recommends is tied to the patch version of expo itself. I measured the ledger diff against the npm registry, how far npm install drifts, and the one check worth adding to a generated project.
Starting with the EAS Observe free tier, and why Crashlytics stays installed
EAS Observe reached general availability on August 20. I looked into consolidating down to one monitoring service and found that native crashes are still out of scope. Here are the free-tier limits and the setup details that trip people up.

expo-doctor passes on API level 35. Here is what its 22 checks actually cover
I opened the expo-doctor 1.20.4 bundle and listed every check it registers. Only one looks at store requirements, and its threshold is still API level 34.
After Bumping targetSdk to 36, Which Part of Your Dependencies Should You Actually Read
I opened six real dependency AARs and counted what they contribute to my manifest. Not one declares targetSdkVersion, and twelve permissions arrive that I never wrote. Here is what to check before you submit.

A tilde in package.json does not mean you are on the newest patch. The file that decides what actually gets installed is package-lock.json. Here is what npm did when I ran the checks myself.
The Remote Config keys you add after your release path closes are invisible to the build already on devices
A record of recounting what I can still change remotely before my release path closes. A key you add in the console does nothing unless a build that reads it is already on devices. Which switches to ship in the last build, and a shared-defaults bug I measured.
