Device name not showed at first connection #650

Hi, i am experiencing a weird problem. Let me explain. I have an esp32 based device that, when activated, starts to advertise its name waiting to be connected. On the other side i have a IOS application that scans for a particular device name and when found it connects the device. The problem is the first connection on a new (never connected) Iphone. What happen: The application try to find the proper device name with no success and so there is no connection So , i open BLE scanner app on the same phone. After a refresh (or a couple) i am able to see the proper name advertised. I go back to my app but the device name is still not found. Then i go back to BLEscanner, refresh the search and i am able to see the device name, i push the connect button, and it connects. After this, i disconnect blescanner, and go back to my app.... and it connects with no problems, and this will remain true for all the subsequent connection attempt. I read about a similar issue in the past about the device name , and i think it can be a part of this same issue but i was not able to find a solution. I had no this issue with bluedroid. I there anyone with the same problem ? suggestion?

It seems that i am the only one having this issue...

Sorry, I don't know why this would be other than to say that the device name needs to be advertised in the advertisement data for it to be seen in scanning.
