If your token's metadata isn't displaying properly on mainnet, the first thing to do is ensure the metadata is correct on-chain. If this is displaying correctly and looks as intended, then display issues are commonly associated with the platform.
To verify the metadata, on the token summary page:
Click the 'View metadata' button. Here you'll find the arweave link to your token's as well. Please verify that this has been uploaded
If you're having display issues on the platform side, please ensure the size of file the platform supports, media type and permissions.
