2 problems

Hello to all. I have two problems. The first is that for a few days my “Elite Drivo” trainer no longer connects in bluetooth mode. The second is that when I train with the PC everything works perfectly but at the end of the training I don’t see it on “Companion” or on “Strava”. What can it depend on?

Among other things, I also finished a training session of the Zwift Academy but although I see the date when I did the training, it did not include it in the total calculation.
