However, in general, if you are experiencing a Facebook login failure on the InsTube downloader app, there could be several possible reasons.
Firstly, it could be due to an outdated version of the app. In this case, you should try updating the app to the latest version, as newer versions often come with bug fixes and improvements.
Secondly, it could be due to a connectivity issue. Ensure that your device is properly connected to the internet and try again. You can also try switching to a different internet connection, such as mobile data or a different Wi-Fi network.
Thirdly, it could be due to incorrect login credentials. Ensure that you are entering the correct username and password for your Facebook account.
Lastly, it could be due to Facebook security measures, such as two-factor authentication or login alerts. In this case, you may need to follow additional steps to log in, such as entering a verification code sent to your mobile phone or email.
If none of these solutions work, you can try contacting InsTube downloader support for further assistance.
