Strength Bars don't seem to be decreasing as they should.
I have been using Duolingo for a few weeks now and love it! Those pesky French questions are tripping me up though!
Anyway, I have opened the app for about 5-7 days now to see my strength bars all full. I know this shouldn't be the case. I'm pretty new to the app and though I practice often I wouldn't say I know all of the lessons I have done well.
For a while I kept getting a notification saying 'Duolingo can't connect'and I would have to re-open the lesson to connect.
I wonder if this is the case?
Ah, humanity. This is the first time I've seen a complaint that the skills don't decay fast enough, although I've seen lots about them decaying too fast. That said, you should be able to choose any skill in the tree and simply do a strengthen - it will present you with a more or less random set of sentences from that skill. You might need to do a log to keep track of what you've been working on. Or you could choose the general strengthen option, which should present you with your weakest areas.
install the user script "DuoLingo skill strength viewer" and manually select the skills which you want to practice (simply ignore the others no matter what the strength bar is)
for vocabulary skills switch to a 3rd party flashcard software like Memrise, AnkiSRS, FlashCards Deluxe, SuperMemo, etc. with a proper spaced repetition (SR) algorithm and more transparent way WHAT words should be reviewed daily / weekly
personally I am focusing DuoLingo for the grammar skills
I randomly do some excercises for the rest of the vocabulary skills (I do not care about their SR)
manually select the skill to practice, do not use the global "strengthen skills" button:

Memrise: There are "DuoLingo" clone courses for selected languages where you can freely choose a level and re-learn + review the words there, e.g French: https://www.memrise.com/courses/english/french/?q=duolingo
There are three longer courses with 49h, 29h, 39h worth vocabulary material.
