Is FBA is the only way? Currently Trying FBM

Hi everyone I started selling on Amazon almost 10 years ago then took a break in 2020(covid affected our supply chain) up until 2025 when we rebranded. I decided to start as FBM just to see what’s up, but having some issues :

1) We are brand registered, but can’t find our product unless it’s in quotes : “Brand ABCDE”. The brand name is unique. 2) Trying various ad campaigns : auto/manual targetting, dynamic bids etc, used higher bids than suggested(even $10/click) but still no impressions after 3 days, amazon support is useless : try increasing your bids, no way our bid was the issue. 3) We have 100% featured offer (former buy box)

So my question is, do we get to deal with all this BS because we are not FBA?
