I decided to try FCMFix out because I've been experiencing persistent issues with WhatsApp alerts on my OxygenOS device. Sometimes the alerts would be delayed, other times they just wouldn't appear at all. Unfortunately, my experience with FCMFix hasn't been very helpful.

While I still receive the regular WhatsApp notification, I also get a notification from FCMFix around 5 minutes later. When I open the FCMFix app, there are no new alerts or messages waiting. This just adds another layer of confusion to an already frustrating problem.
