I found that after adding quick calories the app acts as if you haven't done it but if I then sync straightaway they show up.
Also it took about eight attempts to add myself to the "affects me too" count on your post.
Unfortunately not Mairwen. I tried the syncing idea suggested by Lilbiddy but it seemed still a bit hit and miss for me. I've found just waiting it out sometimes works and the numbers seem to decide to appear hours later. But no, it's still not working how it should unfortunately.
I am having the same issue. I tried everything, even creating a new fitbit account and completely factory resetting my phone. Uninstalled and reinstalled fitbit app, made sure it was the current version...everything. I have had 2 chats with customer support. In the first instance, I was told to repeat many of these attempts, which proved unsuccesful. Then, I called fitbit and the person I spoke to said "maybe the new app update doesn't support quick calories add." I find that very hard to believe as the icon for adding quick calories and the functionality to add quick calories is still part of the app. All in all, and having dealt with customer support twice, I'm having no luck whatsoever getting this problem resolved. The phone operator also seemed exasperated and bad tempered with me, acting as if everything was working fine and it was my inability to use the app which was the problem. I've used this device and app for quite some time and 'quick add calories' was working perfectly fine until a few days ago.
Not 100% of the time no, unfortunately. But what I have found is something that seems to work most of the time. It may have actually been what Lilbiddy was suggesting all along and I misunderstood, I was going back to the main screen to sync after adding calories. But what I've found is if I add the calories and then pull down on the next screen to save or sync or whatever it is doing, it does seem to save them properly most of the time.
Best AnswerIf you're on Android 12, check for the 3.62 update. I got mine this morning. At first everything looked even more messed up. However once I restarted my phone, the app automatically synced with the meals I had logged via the website for the last week.
If the update is not available to you, log via fitbit's website and the data should sync for you as well post update.
