+# Release Notes v2.2.86
+
+Dato: 2026-05-04
+
+## Hotfix
+
+- Rettet Telefoni UI race-condition hvor server-renderede kald blev vist ved page load, men kunne blive overskrevet med tom liste efter ca. 1 sekund af foerste JS-refresh.
+- Siden bevarer nu initialt viste kald, hvis foerste API-refresh uden aktive filtre returnerer tomt.
