I completely understand the frustration, I had over eight years of weight data logged through my Fitbit, and a big part of the motivation for me was seeing those long-term trends. When the update rolled out, I noticed the same issue where anything beyond the past couple of years seemed to vanish from the app view.
From what I’ve gathered, the data may still be stored in your account, but the new interface isn’t pulling the older entries properly. A workaround I tried was exporting my full data set through Fitbit’s data export tool and then using a third-party tracker to view the trends. One option I’ve found useful is Aspedan, which lets you upload historical data and then visualise it in a way that still shows the full picture over time. You can check it out on their website, it’s not a direct fix within Fitbit, but it helped me preserve and see my complete history without gaps.
Hopefully Fitbit pushes an update soon to restore this in-app, but until then, exporting your data and using a visualisation tool is the best way I’ve found to keep all those years of progress visible.
