My M51 does not cast within 5 GHz

Hi guys,
A bit strange problem and not even sure how to google or fix it...
I always used to cast youtube and other videos from my Samsung S9 to Sony Android TV (2017) thru my WiFi 5 GHz home network. Recently, I bought Samsung M51 (love the battery) and this phone for some reason does not want to cast anything within 5 GHz network (though connects to it), but it is absolutely happy to do that if I switch router to 2,4 GHz mode. Switching my router to 2,4 GHz completely is not an option since it results in speed drop on all my other devices. Thus, I was trying to figure out how to force my M51 to use only 2,4 GHz, but understood that Android removed band frequency selection feature. Neither I was able to fine tune my router to use 2,4 GHz specifically with this device, while doing 5 GHz for the rest.
Apparently, I am lacking some essential technical knowledge here. Please help. Thank you.

Try one of this links it worked for me

Link to Google Play store Android System Webview. From here, please click UPDATE. Reboot once update is complete. https://play.google.com/store/apps/details?id=com.google.android.webview

If you do not see an option to update when you open the previous link, open this link to Google Chrome and select update to resolve the issue. https://play.google.com/store/apps/details?id=com.android.chrome
