The app download is stuck or will not install
Each app is about 16 MB; on a slow connection it can take a minute or two. Please: (1) open this page in Chrome, not inside WhatsApp, Gmail or Instagram (those in-app browsers stall on APK files); (2) when the download finishes tap Open in the Chrome download bar or notification; (3) if Android says it cannot install from this source, tap Settings, switch on Allow from this source for Chrome and go back; (4) if Google Play Protect asks to scan, let it finish, or tap More details and Install anyway (the app is not from the Play Store). Still stuck? Write to hello@thinkbrandfirst.com with your phone model and what the screen says.
