When I search for a product using the Amazon app it shows me an Amazon product instead e.g. echo. Completely unrelated to the search I requested which was for a SanDisk product. It seems I'm being forced by Amazon to look at their products which is annoying.
I'm sorry you're having this issue when using the Amazon Shopping app.
I would try clearing the cache of the app if you have that option on your device, or deleting and reinstalling the app.
If that doesn't help - we need a few more details to assist. Are you able to scroll down and see the correct results, in this case SanDisk? Or are you only seeing Amazon-branded products and/or ads? Also, which device are you having this issue on?
