I follow several influencers on Instagram and YT with over !M subs that have been locked out of their accounts with no explanation and no response to their information requests. One opened up a Twitter/X account to try to request help, but unfortunately, since that account was new, he didn't have much traction.
> My Google maps account
What is a "Google maps account"? I have a Google account, which I use with their various services.
Google business account. Which is different than a Google ads account - I was able to get in touch with Google ads support easily but they said the two departments can't talk to each other. It took several weeks to get through to business account support.
Edit: and note, I log into both of these via my personal Google account, which is also a different thing.
My Google maps account was blocked also when traveling, but fortunately after several weeks I was able to get that one back.
With Instagram though I just had to make a new account. I also have a Meta Business account (business.facebook.com) and the Instagram account was linked there. The Facebook business account, pages were never blocked though, just the Instagram one.
Unfortunately after a few months I just had to accept it and make a new account. I hope you have more luck, but I assume it's the same with any Meta products. There is no support you can contact, no way to get redress. If it's possible, try to avoid using Meta products to build anything. I understand that's not always possible though, I run a bakery and absolutely must have both Google Maps and Instagram, much as I wish I didn't.
