Problem with Changing Weight of exercises in Connect App!

 Hm, it works all right on my side - just have tried it exactly in this way. But I still do not understand - you wrote that when you enter 57.5 it gets transformed into 575 (as if the comma was ignored). However, from the screenshots you posted it looks like the 72.5 got transformed into 453,6.

Anyway, there is some inconsistency - the edited number is with a decimal dot (72.5), while the final number is with a decimal comma. And the keyboard on the edit screen in fact seems to be showing two commas, instead of a dot and a comma. It looks indeed like a bug in the localized German version. Try using the bottom button with the second comma, but since it is greyed out, I suppose it won't work. The upper button with a comma outputs a dot in fact, and since your number format is set to a decimal comma, it is not accepted.

Well, you should report the bug to Garmin, but make sure you explain it clearly, because it took me really long time to understand what your problem is, and I suspect it will be the same case for the developers.

However, you have several workarounds available:

• you can use the web app instead,
• you can try changing your number format to use a decimal dot instead of the comma (in User Settings on GC Web)
• well, you could change the Android language to English, but that's likely not an acceptable solution, just mentioning it for the record here
• you could enter the number with the true comma in another app, using the full keybord, copy it, and paste it into the edited field (you need to hold the field for 2-3s to get the paste menu)
• you can simply round the values up to the full integer numbers. The number there are for the record anyway, and do not serve for any Calories calculation, so the decimals are pretty unimportant
