Same issue! Just after upgrading to Android 10.
Tried to unistall and re-install the Direct Call but it does not work anymore!
Help: it was my favorite tag edge!
@teok31: This feature may have been removed from the Edge app, however there is a way you can work around it. Simply open the Edge Panel on your Home screen > Tap the cog symbol in the bottom right > Apps > Edit > Add Phone and Contacts to your Edge Apps. Alternatively, select Tasks > Edit > Make Calls > Select the contacts you want to create a shortcut for. I hope this helps.
