I just received a notification from my Samsung Galaxy S10 that it was dangerously low on storage - 127 out of 128 GB used. When I drilled down to see what items were using high amounts of internal storage, I discovered that the Bose Sleep app was using 55 GB! I ended up uninstalling and re-installing the app. After re-installing, it is now using 139 MB and the internal storage is back to 75 out of 128GB used.
I'm curious if anyone else has observed this behavior in the Bose Sleep app on Android? I am only using the default sounds, etc. - I have no idea what could possibly cause such high storage use. Other than this, the app and Sleepbuds II have been working very well for me (and have become indispensible). I guess I will have to keep an eye on the app's storage usage and see if it starts increasing again. I am using the latest version of the app - 3.0.9.
