Myfitnesspal has started negatively adjusting my calories. Yesterday for example Garmin increased my calories by 744 and Myfitnesspal decreased them by almost 300. I had dug an allotment, fast walked a couple of kilometres to the gym and done an intensive spinnng class! This was more than my normal average activity. Anyone having the same issue?

    Was -300 the total of your calorie adjustment? Or was your exercise 744, and then -300 for the gain Connect adjustment, giving a total of +444 calorie adjustment?
    It can be perfectly normal, depending on the circumstances. If you selected a higher activity rate in Garmin and all of your activity for the day was exercise (inactive outside of exercise) then it's normal to have the line 'Garmin Connect adjustment' show a negative number.
    On top of that, Garmin sends gross calorie burns to MFP for exercise, but your BMR calories are already taken into account by MFP, so those BMR calories from Garmin exercise are deducted via the Garmin Connect adjustment. For short exercise it's barely noticeable, but when doing multiple hours of exercise, it can add up to a negative adjustment of several hundred of calories.

    Screenshots would help to understand if there is an issue. In any case I would recommend comparing your TDEE in Garmin with the TDEE that MFP is receiving from Garmin (tap on the Garmin Connect adjustment line in the diary and then continue into you see a screen that shows you the data received from Garmin.
