This may seem to be a “drastic” solution. How about deleting storage and cache from the Reolink app. This should remove everything about every camera. That’s in Settings->Apps->Reolink. Although it may seem silly, I am not confident that removing and reinstalling an Android app actually clears the saved data.
Thanks for this. Clearing the cache & data fixed the issue for me.
For Android Oreo users like me, you have to go to 'SETTINGS' -> 'STORAGE' -> 'OTHER APPS' -> 'REOLINK' - then clear the cache and data.
I do have another question. After clearing the cach/data, the app behaved like I had installed it for the first time and reminded me to register the device to increase the warranty to 2 years and 6 months. Do I need to do this again when I had already registered it before clearing the cache/data?
