Pop-Up Options in Team Member Lists do not work on iOS

In the last few weeks I noticed, that the options ("kick out of the team", "put on waiting list", "write message", etc.) that normally pop up when clicking onto a team member in the list does not work, it just gets me the options of calling the person with the description: #tt-tt-"ID-Number of the person". I used to be able to see, when the last pick up date was, this is also not possible anymore on iOS devices. I tried it on the latest iOS Version on the iPad and iPhone. This problem is only there in the team list, nowhere else, where the same layout/pop up windows appear (for example the slots). I tried on Safari and Chrome.
