Zenfone 8 MMS Issue - Can't download/view images in Messages app

[flameimperishab]

Hi,
I cannot seem to view MMS images in the Messages app on my new Zenfone 8. I checked my APN settings and they all seem correct. I know I have received the MMS as there is a a "Download" button for the message but when I press it nothing happens. Is this a known issue withthe Zenfone 8 and is there a fix or workaround as it is very annoying.
Thanks.

Would love an answer for this as well. Also having the same issue. No problem with Sim on previous phone (galaxy S9). ZenFone 8 has the download button for the MMS and does not let me send them either. Reset already tried.

Same issue for me too with Zenfone 8 Flip on Exetel which uses the Optus network. Even got a replacement SIM card in addition to all the steps others above have tried. Still no MMS.
