It looks like Amazon is starting to hide some reviews to protect against data scraping bots, and in some cases it is affecting real (non-bot) customers.

Were you signed in when you got the message? All of the sorting / filtering / search options are showing up fine for me (as a signed in user).

I haven't seen this yet. Never used the app - I use the mobile site usually while logged in (but not always). Unfortunately a few features are missing (like being able to see all items for some reason by a specific seller) but otherwise it works well.

Is this you on X or did you link to a random post ?

Hard to know how to feel about this. Bots and such have really ruined the value of customer reviews. The best that can be said is they don't work as intended. The question is whether Amazon can actually fix this problem rather than continuing band-aid over it.

Amazon has also changed their email receipts to be worthless. Previously, you would get the product name and price paid, giving you a minimal record sufficient for tracking. Now you get an email that says N items, broadly categorized (housewares, pets, clothing) and no pricing information.

Clearly a customer focused decision.
