Immersion is something on Duolingo
But today it disappeared for everybody.
Very strange but then it came again
must have been a glitch
The Immersion has often disappeared
but
often for a temporary period
However If the articles still exist,
and you can access them
through your stram
during this time
then it is probablly
just a gllitch
Then not something to be concerned
