+> | :exclamation:  Breaking changes in Obsidian 1.7.2 (and newer) - no fixes available|
+> |----------------------------------------------|
+>
+> Obsidian team introduced some more breaking changes in a not-backward-compatible way starting from Obsidian 1.7.2.
+>
+> The observed issues are minor, no fixes available (a work in progress with unknown release date):
+> - the custom sort plugin is **unable to automatically apply the custom sort on start**
+>   - prevalent on mobile
+>   - for the _Lazy Plugin Loader_ plugin occurs by definition
+>   - **workaround**: custom sorting has to be applied manually via the ribbon icon or the command 'sort on'
+> - the custom sort plugin **keeps showing the notifications** with each change to any note
+>   - **workaround**: disable the notifications
+> 
+> For more details of the observed misbehaviors you can go to:
