Significant delay when navigating to the den in Minecraft Bedrock on iPad

Please ignore my previous report, it was submitted in the wrong language

Hello,
I'm having a problem with Minecraft Bedrock on my iPad. When I enter the portal to the Nether, the game lags a lot before it takes me to the Nether. Sometimes it takes more than 10 seconds, and the game freezes a bit before it takes me to the Nether. This happens even in new worlds without add-ons or shaders.

I hope the performance when entering the Nether is improved, as the issue impacts the gameplay experience.

Additional Information:
• Device: iPad Pro (12.9-inch) (5th generation)
• Version: [ Minecraft version 1.21.81]
• Mode: Singleplayer
• No add-ons or mods

Thank you for your efforts
