Fitbit apparently won't be providing regular updates, so here is my advice as a computer scientist who works in tech support (for another company). If you are using Android version 3.37 of the app, released January 20, 2021, and you cannot sync your device since updating the app, then this is almost certainly the problem you are having. Android version 3.37 has sync issues.
DO NOT WASTE YOUR TIME TROUBLESHOOTING. I spent a few hours on this, and I am a computer scientist that has been using Fitbit devices for years now. I tried everything. Other users have also spent hours. NOTHING resolves the issue. The problem is the app. However, I did find a few possible workarounds (see below).
DO NOT CONTACT FITBIT TECH SUPPORT. They will waste your time, and they are still giving people bad information, claiming this isn't a known issue. I wasted 2 hours with them yesterday / early this morning, and they still refused to admit this is a problem with the app.
DO NOT DO A FACTORY RESET. This is a part of the standard troubleshooting steps for sync issues, and so tech support has been directing people to do it. DON'T FALL FOR IT. It won't work, because the problem is NOT your device! If you reset it, you probably won't even be able to use it until the issue with the app is resolved. Even once the issue is resolved, you will need to update the firmware again. It's a waste of time, and it is risky. If it works fine, no problem. If something interrupts it, the device may never work again. It will be a paperweight. It should only been done when absolutely necessary.
DO NOT REMOVE AND TRY TO RE-ADD THE DEVICE FROM THE APP. Again, this is part of the standard sync troubleshooting steps, but it won't work in this case. The app cannot communicate with your phone due to the sync issues. You won't be able to add it back until the issue is resolved with a new app version.
IF YOU HAVE NOT YET UPDATED THE APP SINCE JAN 20, 2021, DO NOT DO IT. The problem is with the version of the app released January 20. The NEXT version will hopefully resolve the problem. Wait for that version.
YOU CAN CONTINUE TO USE YOUR DEVICE AS NORMAL, just without syncing it. Last I heard, most devices keep about a week's worth of data in memory. If the issue is resolved within about a week, you should be able to sync it all once the app is fixed.
YOU MAY STILL BE ABLE TO SYNC YOUR DEVICE VIA WIRELESS. I found a workaround for my particular device (Ionic). What finally worked for me was to use the wireless connection instead of Bluetooth. The wireless is usually used only to sync music, but apparently it syncs the data, too. I connected it via wireless (to my computer) as though I was going to transfer music, but then I didn't transfer music. This synced the data, including my last workout (which had been stuck on my Ionic).
YOU MAY BE ABLE TO SYNC YOUR DEVICE WITH ANOTHER PHONE / TABLET / COMPUTER. This has worked for some users. I have one of those old Fitbit Bluetooth dongles (it came with my Zip back in the day), but it's NEVER really worked well for me, so I've always used my phone. If you have an Apple version of the app on another phone or tablet, I recommend using that.
YOU MAY BE ABLE TO SYNC AN OLDER FITBIT DEVICE. My old Blaze still syncs fine, go figure. Without more information from Fitbit, we'll never know exactly what causes the problem. It seems to impact MANY people, but not everyone.
Here's hoping Fitbit fixes this issue soon! Users have been reporting it for a week now, but Fitbit refused to acknowledge the issue until today. And even now, they are apparently still not acknowledging it consistently.
