Any ideas / tips? I've seen similar topics, but most of them concerned mobile apps - our case is different, because we have web application and rely mostly on messenger's embedded browser. Uninstall the Facebook Messenger app on your iPhone or Android device and then reinstall it. Android smartphones and tablets have different background app settings. So, what can be the difference? Some Facebook application settings? We were testing different configurations without success. On iPhone, select Settings > Messenger and enable Background App Refresh. The way how they implement that seems the same as ours. That is so because its convenient and just works without burdening you with extra configuration steps. The interesting fact is that in some other websites log-in via Facebook in messenger's embedded browsers works perfectly (so redirection to the origin page works). The Facebook app opens links in its built-in browser by default. Without redirection, we are not able to get the token. After providing credentials, the page is displayed as in the attached picture (it says close this tab) instead of redirecting to our website.

One of the most popular sources of traffic will be messenger - and our page will be opened in messenger's embedded browser.Īnd here we have a problem - In opposition to the embedded browsers in other applications (for example Slack and even Facebook app), log-in via Facebook in messenger's embedded browser doesn’t seem to work. We're developing web application that significantly relies on logging in via Facebook.
