PUBG Mobile has multiple sign-in methods, and logging in with Facebook could cause problems on rare occasions. Depending on how you set up your PUBG Mobile account, the game may prompt you to log in with Facebook.

While this may look like a simple request, the main problem kicks in when players fail to log in with Facebook due to reasons beyond their control. In my case, I was somewhat confused by this error since I didn't have much knowledge of Facebook services. However, a quick chat with PUBG Mobile's support team got me up to speed with the following solution method, and here's how you can fix the Facebook login problem on PUBG Mobile.

How Do You Fix the Facebook Login Problem on PUBG Mobile?

The best fix for PUBG Mobile's Facebook Login Problem is downloading the social media app on your device. PUBG Mobile's Operations team also suggested this solution method on a Reddit thread about the Facebook login process.

I could also quickly verify this solution method since I didn't have the Facebook app installed on my phone. To apply this fix:

• Go to the Google Play Store or Apple App Store.
• Search for Facebook and download the app.
• Log into Facebook with your account details.
• Launch PUBG Mobile and wait until it prompts you to log in with Facebook.
• The Facebook app should automatically pop up and synchronize with PUBG Mobile with your permission to complete this process.

PUBG Mobile's Facebook login issue may have different reasons, too, since it can also appear after each game. Compared to the first situation, this looks to be an in-game bug that goes away after manually logging in again. However, considering it might continue to appear after each game, it can test players' patience. 

If your PUBG Mobile prompts you with notifications about logging in with Facebook after each match, you should contact the game's support team.

You can reach out to PUBG Mobile's support by:

1. Click the arrow button next to Inventory on the game's main menu.
2. Tap on Customer Service.
3. Choose "Contact Customer Service" on the bottom left of your screen.
4. Select a category and detail the situation you're facing.

In most cases, such consistent errors and bugs could be device-specific occurrences. By submitting a ticket, you can bring the situation to the developers' attention, and they may roll out a quick hotfix to solve the problem permanently. Once you’re back in the game, you can continue to wreak havoc with the top guns in PUBG Mobile.
