I feel you. A blocker I found is that typically everybody is down in the trenches of the actual project work coding, reviewing, analysing bugs, helping support.

I feel you. A blocker I found is that typically everybody is down in the trenches of the actual project work coding, reviewing, analysing bugs, helping support. Therr is already something more urgent to do. You need buy-in from your team lead/line manager and a critical number of team members that actually want to make a cultural shift, but for some reason cannot. Your regular team retrospectives are the place to address this and come up with an action plan how to bake it into teams processes. One of the possible solutions is to block time in the teams calendar for dedicated "learning". That could be regular "developer forums" or "reading clubs" or what ever. If a document is required to be read before a meeting, schedule 10min in the beginning of the meeting where all collectively read the doc.
