I have said before, particularly in the first year of lockdown that my wife was totally forgotten by he cong. It is only because she upped and complained that she now gets occasional phone calls
That direction to elders to keep in touch was certainly given in the beginning but did they do it? No way!
To my mind the problem starts at the top. When I was an elder we did get told to shepherd our groups. However we had much stronger direction to put in good hours in the Ministry, so shepherding often slipped.
Elders need to be like managers and accountable for seeing and helping their group members.
