Unable to Access WhatsApp on Primary Device

Over the last month, I've been dealing with a frustrating issue on WhatsApp. Even though I can log in from other devices, I can't seem to access it from my own device. Instead, I am prompted to download the official WhatsApp app. This problem is quite bothersome because it's affecting my usage of the app. I urgently need assistance from a qualified technician to resolve this issue. Continuously changing devices is not a practical option. Given the lack of available customer service to handle my issues, I've resorted to using the Xolvie platform to express my frustration.
