a few days passed and my collection still didnt up... @KukaiWallet

Answer 2: If clearing the token metadata doesn't fix the issue, then it may be due to a delay in the objkt API. In this case, you should contact objkt to see if there is a problem with their API. Additionally, you can check the API logs to confirm if your collection is being updated properly. If the API logs show that the collection is not being updated, then you should contact objkt to investigate the issue further. If the API logs show that the collection is being updated, then it is likely that Kukai is not properly reflecting the updates from the objkt API. In this case, you should contact Kukai support to investigate the issue further.

Kukai uses the objkt api, if your collection is up to date in response we get from objkt then you will get the latest collection...to test this first do one thing, go to Kukai settings > clear all token metadata, does this fix it
