On recent versions of Everdo, whenever I hold down the key combo I have set for “Move item up” or “Move item down”, it will only move the item up or down for 5 items at which point it loses the selection on that item and grabs another one and starts moving it. It’s specifically a problem with holding the key combo down, as opposed to pressing it quickly.
I’m on 1.11.14 on the snap version of the app.
