I think I get pretty much the same issue:

Already fixed, but was scheduled for v2.3.3: https://github.com/dovecot/core/commit/4ff4bd024a9b6e7973b76b186ce085c2ca669d3e

As a workaround, you could disable ACL when running dsync: doveadm -o plugin/acl= ...


Judging the 2.2 master src I assume that this patch is also applicable on 2.2.36?
While we are at it: Will the 2.2 branch receive another minor release or is 2.2.36 already the final 2.2 version?
