Hello!
After some receint updates (ex. during last 1-2 months) all the apps disappeared in the apps list.
However, there were 4 of them before the update. At least, the BitTorrent app is running, but not shown in the list.
The Android mobile APP is v. 55, the Keenetic OS is 4.3 Alpha 4 (but this bug was seen on some earlier versions also).
