"Strengthen skills" is buggy
On the web version I recently have noticed that general graphics and transitions have changed slightly, in addition to ads being show aside. That is not a problem, even though the esthetic value has dropped due to owl being slightly out of place, and update bubbles at the bottom now missing. However, when strengthening skills, an improvement over a skill is not shown, i.e. if the skill is actually improved, skill bars are not shown to be improved in any way. Language and skill sections still show correct improvement, but now I have to exit practise every time to check if the skill has been improved. Hopefully, this will be fixed in near future.

I'm having the same kind of problem, I will load the site, perfect internet, just to see 10 topics have dropped. I complete the practice, but my strength bar doesn't go up, it just stays at a measely 4/5. It's been happening for days, and now my skills have dropped to 3/5! It's crazy. I'm starting to cry about it.
Those strength bars are driving me crazy. After bringing downgraded bars back to full strength, I make sure that the owls show up as golden again on the Home page as my last step before I quit the program for the day. However, much to my surprise I find the same lessons that I have left as corrected back to 5/5 status showed up downgraded to 4/5 again when I get back into Duolingo a few hours later.
Who is messing with my strength bars when I am not using the program? After investing a lot of time and effort to reach Level 16, I am beginning to lose interest in finishing the tree. It is demoralizing to type the same sentences over and over again.
It's a spaced repetition thing - the programmers have those reminders to review (the bars losing strength) because people tend to forget stuff a while after we learn it...
i am am using two separate emails for 2 languages on same chrome--one is acting up (no proper strengthening on timed practices, no progress, no upgrade in skills, etc) the other is working fine--what is solution to repairing this situation. thank you.
