Unable to Log Into Arena of Valor via Facebook

I’ve been playing Arena of Valor for years and have always logged in using my Facebook account without any issues. However, recently, I’ve been unable to log in through Facebook, and I’m unsure why this problem is happening. I’m concerned because all my game progress is linked to that account, and I don’t want to lose any of it. When can I expect this issue to be resolved? Is there any timeline for when the Facebook login functionality will be fixed?
