Forerunner 225 on v2.90 per Express
Express is on 4.1.23.0
I have the same problem as Retimus in this thread. Connect shows 20 updates in the blue circle of the tray: languages I don't need, Time Zone Map v18.00, and GPS Chipset Type M426 (Fitness Region File). I get to Connect via Express, click "send now", Express opens and syncs, then reports that I'm up to date.
I can sync workouts and activities, though I did have a workout lose a step and its title when I sent it to my 225 from Connect on my phone.
I tried to update these with WebUpdater and installed the languages but the other two files weren't available; updater gave every indication I was up to date. I then used Express to get to Connect which still shows 20 updates. They come back every time I connect despite dismissing them, and I get a notification on my phone when I connect the 225 to the Connect mobile app.
