# Why a PromoStar mobile notification did not arrive

> Fix missing PromoStar mobile notifications on iPhone and Android: Home Screen install, phone and browser settings, Focus, battery and Data Saver, and PromoStar's one-alert rule.

A PromoStar notification can go missing because of a phone setting, how the app was installed, or PromoStar's one-alert rule. Work through the group for your phone, then the PromoStar group.

## iPhone

* **Not opened from the Home Screen.** iPhone sends notifications only to web apps added to the Home Screen, and only on iOS 16.4 or later. See [Install the PromoStar mobile app](/help/mobile-app/install-the-promostar-mobile-app).
* **Notifications are off.** Open Settings, tap **Notifications**, tap PromoStar, and turn on **Allow Notifications**.
* **A Focus is on.** Do Not Disturb is a Focus and silences notifications. Check Settings, then **Focus**, to see which apps each Focus allows.

## Android

* **Chrome blocked notifications.** In Chrome, tap **More** (⋮), then **Settings**, **Site settings**, **Notifications**. Allow them for PromoStar. Chrome can also block a site automatically.
* **You cleared browsing data.** Deleting **Cookies and site data** and **Site settings** removes the permission. Sign in and tap **Turn on** again.
* **Battery saving.** Doze and App Standby limit what apps do in the background and can defer notifications. Open Settings, tap **Apps**, tap **Chrome**, tap **Battery**, and choose **Unrestricted** so Chrome can run in the background.
* **Data Saver.** On a metered network it blocks background data for apps. Turn it off under Settings, **Network & internet**, **Data Saver**.

## PromoStar

* **Notifications are off in PromoStar.** If the control shows **Turn on**, tap it and allow the prompt. Your phone asks for permission only after that tap.
* **You re-added the app or switched accounts.** On iPhone, a re-added app starts with fresh storage. Sign in, then tap **Turn on**. Do the same after you switch to a different PromoStar account on the same phone.
* **The phone was removed.** If you selected **Remove** next to the phone on the **Mobile App** card, it gets no more notifications. Reopen the app on that phone and tap **Turn on** again.
* **"Notifications are blocked for PromoStar."** Allow them with the iPhone or Android step above, then return to the app.
* **The post already had its alert.** Each post sends one alert per phone, and posts due before you turned notifications on send none. **Ready now** lists any post you missed. See [One alert per post](/help/mobile-app/get-told-when-a-post-is-ready#one-alert-per-post).
