Battery saver switching wifi off when phone locked

I’ve recently installed Avast Battery saver on Samsung S7 and have had a issue with wifi being turned off automatically when the phone is locked, then re-activates when I unlock the phone.

I have disabled all of the ‘profiles’ as I don’t want these

What other settings are there as I think I’ll soon be uninstalling the app as it’s stopping important messages being received

Same here, i tough it was Anti-Theft but no.

My behavior is different, it turns Wi-Fi on for a second when i unlock the screen then switch it back to off.

All Wi-Fi are disabled on my side too.

Same here with lg phone…but wont turn on until restart,then will stop as soon as phone sleeps
