Tagging people on Android app

[WhoAreYouTalkingTo]

Samsung 25, latest software.

If I tage more than one person, every time I tag the second person if just keeps tagging the same person again. If I delete the tag, the screen jumps and when I go back to what I'm writing it has tagged them a million times again, but with another @ symbol at the end. See below.

Hi there @WhoAreYouTalkingTo. Thanks for getting in touch.

We are aware of this issue that's affecting Android users. We're looking into it at the moment but to be honest, it's not looking like it's going to be a quick fix. We'll let you know whenver we had an update but want to be upfront that this is one that may take a bit of time. Thanks for your patience in the meantime.

Thanks for the honesty
