removed from the EU app stores, right?

Correct. Just the EU app store.

Sold my company more than two years ago, and they failed to transition any of the information to their company account and/or address.

It's been like pulling teeth trying to get Apple to update our information because of the specific documentation that they want and the layers of ownership.

Yeah we have a secondary developer account from an acquisition and need Apple to change the information for it to match ours (they rejected our Trader status documents with our correct info since it doesn't match the outdated info on the account), but no matter how many or through which avenue we try to contact them, it's crickets, so that app is gone from the EU for now.

We finally got ours sorted out.

Address is wrong (old location), and I submitted old documents (pre-acquisition articles of incorporation and sales tax filings to satisfy their inane requirements), but got our app back into the EU store.

Might check documents collected through the due diligence phase to see if you can dig up things that match.

At least I was able to get us back in the store, and now I have a longer timeline to figure out how to get the information corrected, or transition the app to their account.

"Trader" contact info simply means the business's address, and phone or email.

It's a legitimate requirement, since the E.U. generally already requires this for all businesses in the E.U.

"Independent developers and small companies may not have dedicated business addresses and phone numbers to provide to customers"

So this is an invalid concern right?

Unless they're homeless, they have an address. When you run a business out of your home, your home address and your business address are the same.

And the law requires a phone number or email address. As at least one of these are required as part of the business registration process or for various business-related compliance, it's simply not possible for a legitimate business (whether solo or company) not to have either.
