WhatsApp having trouble installing the app

Hi,
My app WhatsApp gives me this error every time I want to open it. I heard that the WhatsApp are experiencing some issues but it seems like I am the only one with this error. The app is working just fine on my friend devices. Can anyone tell me what is happening with my phone and my app? Thank you!

Tap and hold the item, then tap Retry.
If you’re trying to update an existing app, and the problem continues, you might need to uninstall the app then install it again.
Retry close
