Unsupported argument type: ActiveRecord::Relation

I believe this is possibly in relation to some of the recent modifications to deliver_now code in one of these: #9310 #9311 #9312

It's affecting whether digest emails are being sent!

I would like to work on this @jywarren, can I ?

Hi @manishaag7 I think this one may be very tough to debug without access to a production server. Can you try something at https://code.publiclab.org ?
