From 9dc57122d991d54ea6750448ba88c8763a569830 Mon Sep 17 00:00:00 2001 From: Till <2353100+S7evinK@users.noreply.github.com> Date: Fri, 19 Aug 2022 15:32:24 +0200 Subject: [PATCH] Fetch more data for newly joined rooms in an incremental sync (#2657) If we've joined a new room in an incremental sync, try fetching more data.
