I already have the bnb on my account it won't load the pancake swap when I go to buy the coins, it is not getting to the point where I can see the bnb that is in my wallet on the pancake swap exchange to buy the coins
You will be fine if you continue to save BNB without buying other coins at this point because BNB is also a very good coin for you to save and also to use on any job you need right now. So you don't have to worry or worry about the assets you have.
I think OP not worry with his BNB assets but asking why not load when access Metamask trough iphone, usually I use Metamask trough android only and most active access with google chrome add on Metamask. I don't have iphone mobile and little knowledge about problem faced by OP why can't load BNB network on iphone mobile access. I think have trouble with IP network usually depending have several countries can't access by metaamsk add on chrome without use VPN, but still can't understand yet the OP trouble if not show about his picture where are trouble and can't load BNB network.
