Why can't I send pictures/files in whatsapp or Viber

[AC Question]

Just bought a Samsung galaxy A9pro (A910F international version) and everything working except I can't send media in whatsapp or vibes. I can send text and receive text and media I both. Tried All the recommended fixes, ie; uninstalled and reinstalled. WiFi on and off etc. Can you help?

What is the exact wording of the error message you are getting?

The green circle stops, the picture goes grey and it just says "retry" across it .

Check all your permissions just to make sure.

I tried sending a picture on the free WiFi at my local car dealer and it went straight away on WhatsApp and Viber. So it must be my home wifi where the problem lies.
