I used to buy MTMTE/RID season 1 on comiXology, but now I can't search TF comics there. Even those I've purchased don't appear on 'my books'. I suppose they are region-locked due to publishing issues. (I live in South Korea.)
Is there any way to buy and read them legally?

 

I seriously doubt they can remove digital content your already purchased from your account. They can prevent future sales but they can't take away existing purchases

 

I think I saw you in the native forum. I also purchased IDW's comic books from Comixology, but it became inaccessible. The only way I know is to buy comics directly on the IDW website.

 

Recently, the IDW website has been updated and region restrictions have been included. Now I can't buy Transformers comics on IDW's official website. Comics that have already been purchased can also be seen on the list, but they cannot be read. The solution is to use VPN. I'm going to find a commercial VPN because it's too slow to read the comics with a free VPN. When I asked IDW about this, they said they don't provide transformer comics to specific regions. I'm really curious about the reason.

 

I found out that I can read comics without VPN when I use IDW's official mobile application. Now, I can turn on VPN on my PC for purchases and use mobile for reading. I hope it will help readers in locations where region restrictions are applied.
