Strength Activity After Update

I have the same. First workout since the update and it's thrown all my timings off.

I have used the strength app and it works as it always has.  

Mine displays sets and then when I press the finish I press the button and it goes to the rest field.  

Maybe try a watch reset or remove the strength app from your favourites and then add it again. So far as I can see, it hasn’t changed on my watch.  

Same problem here. I went to settings and turned on the count rep ant started to work as before, but it shows a screen to input the number of repetitions...

It always does show this screen as it often gets the reps wrong.  

Had the same problem with the „rest“ screen in some activities. It started with 8.05 beta and is still there with latest sw. 
so I did a Factory reset today and this resolved the case. Seem that the saying „do a factory reset at major sw updates“ is still valid at Garmin devices

Same problem in the German version. Instead of sets (German: Sätze) it says rounds (German: Runden) now. Absolutely awful. Is there any other solution than a factory reset. I did a lot of customizing and it would be sad, if all this would be gone...
