I am a Software Architect with decades of development and leadership experience. I have a new Manager since 6 months. Previously we both were colleagues as Architects, but when my previous manager quit, he was promoted.
When he got promoted, he made it very clear to everyone that he does not want to be playing Architect role anymore, also that he would not have managed it time wise anyway to fulfil both Manager and Architect roles.
We usually get along well and he seem to respect my experience. But since some weeks, he is interfering and micromanaging technical details in a way an Architect would do. Given his background, I took it lightly initially -- after all, it is good to have a manager who understands technology. But nowadays he attends meetings which are only meant for Architects (he has those meetings in his calendar from Architect days) where he is pushing his opinion. He attends architecture workshops which I conduct for the development teams and undermines the decisions I wanted to take. As they also report to him, they have stopped listening to me, though technically they seemed to agree with me.
I am quite disturbed by this - I do not want to give an impression to the teams that I am insecure or so by his presence, but how can I remind him that he has a new role now and him playing the old role creates a conflict of interest? I thought of contacting his boss by chat to mention this, but not sure whether this would damage the relationships
EDIT:
I'd like to clarify -- in my org., both developers and Architects report to a Head of Development. Several Head of Developments report to CIO/CTO. So we have several Architects working under different managers, with Architecture group (a virtual team, so to say) having the overall responsibility to make technical decisions to protect the interests of the company (e.g. data security, compliance etc.). Here the source of conflict is that my manager on couple of occasions exercised his authority in a way that compromised established architectural guidelines
