Activity does not appear on the calendar

Hello,
I did a cycling session instead of running today. It seems to have been recorded by the software, as I received a notification and was able to give my feedback, but it doesn’t appear on the calendar, even though it’s included in the total on the right.

That’s the first problem.

I then deleted today’s planned running session, hoping to see the cycling session I had completed appear, but then I got the message “update failed.”

So I regenerated my training plan because it seems to be the only solution, but now I’m stuck with this bug where there’s nothing for next week (the fitness/fatigue numbers indicate the opposite). I don’t know if it’s “working in the background” but I don’t see any indication that it is (like an updating button)

Thank you.

Everything seems to be back to normal after a few hours, but now the problem is that I’m back at build 1 when I was about to start build 3… I have 15 minutes of L3a to do, even though I already did 20 minutes of L3a last week, I think I had 15 minutes of L3b to do this week in the original plan (So I added the session manually.), so I dont know what to do, is a rollback possible ?
