Help Android File Transfer not working

[hawkeyefxr]

This is the nearest to my phone.
Got a new phone a couple of weeks ago a Samsung A21S, Android File Transfer was already installed and working on my Mac. The A21S connected a couple of times but has now stopped. The Mac can see my phone (looked in system info and it there ok).
Tried different cables (which have worked in the past)
Tried airdroid, thats a complete PITA!

When the cable was connected the phone does not come up with the screen below. I have spent half a day looking for info on this and it's driving me kin mad!!!!!
Any help appreciated.

Don't know anything about the software that you mention, but I would just use NitroShare.

Simple, wireless transfer.

The app goes onto your device, and there is a version for your PC.

Place both items onto the same Wi-Fi and it will work fast and smooth.

Which AFT version? It's not updated often, but I had such problems a few years back which were fixed by updating the app.
