Meizu MX 4 - Ubuntu 15.04 (r3).
Did the Telegram update to v2.5.4 today, and immediately afterwards had this Btcfoo.com Official group on display, many people entering this group permanently. I didn't add this group !
How do I get rid of this group ? Answering the dialog 'are you shure to leave this chat' with ok doesn't do anything. Sucks.

Hi, using the hotspot function in ubports ( Ubuntu 15.04 (r2)) is working, but there is no symbol in the status line to be seen if using hotspot function.
I'm not really shure if there was a symbol using ubuntu OTA-15.
