For anyone that wants to get their steps and other data logged to Myfitnesspal, while the direct integration is broken, I got it to work as follows.
You will need to download an app from the Play Store called Fit To Fit, this links your fitbit data to Google Fit. Which still works.
So what you need to do is:
Use Fit To Fit and link Fitbit to Google Fit - make sure all options are selected.
Then link Google Fit to Myfitnesspal, but again select all options, you'll need to scroll down in the list and select everything including steps as these aren't automatically selected.
This then seems to link fitbit to Myfitnesspal and I get steps and calories. Although had to tap on the steps panel in Myfitnesspal to get the sync to run, hopefully this will be automatic going forward, but I will update.
Convoluted and less than ideal, but seems to work, at the moment.
Can't speak of there is a similar method for Apple or not.
Good luck of you try this.
