Phone / Radio no longer works on mobile devices

Summary / Zusammenfassung

Calls and radio conversations can no longer be made on an iPad in a web browser. This worked perfectly before! Strangely, it worked once in a session, then never again, and not before that either.

Steps to Reproduce / Schritte zur Reproduktion

Started a session and also accessed the session on iPad via Safari alongside the Windows client. Tried the same with Edge and Firefox on iPadOS. No success either way—I can neither see calls, contacts, etc. nor interact with them. This worked in the version before the latest one.

  1. Go to ‘…’ / Gehe zu ‘…’
  2. Click on ‘…’ / Klicke auf ‘…’
  3. Scroll down to ‘…’ / Scrolle nach unten zu ‘…’
  4. See error / Fehler sichtbar

Expected Behavior / Erwartetes Verhalten

The web interface should also work on iPad!

Actual Behavior / Tatsächliches Verhalten

Impact on Usage / Auswirkung auf die Nutzung

Massively restricted usage!

Minor: Small / cosmetic impact. / Kleiner / kosmetischer Einfluss.
Moderate: It disrupts some workflows. / Beeinträchtigt einige Arbeitsabläufe.
Critical: I can’t use the platform at all. / Die Plattform ist nicht nutzbar.

Screenshots or Logs / Screenshots oder Protokolle

By the way, when is the promised iPad app actually coming back? That would solve the problem too…

Addendum:

Once you switch places or sessions, for example, it no longer works. After you completely clear the browser data for Simdispatcher, log in completely anew, and load an existing session (already open on the PC with the desk selected), it works.
