`gpg --pinentry-mode loopback` used to ask passphrase once but now it asks always

In short (Edit 1): How to make gpg -qd --pinentry-mode loopback out.gpg cache the passphrase for a period of time in the cli. It used to cache but now it doesn't. Edit 2: I have tried this thing in both Kubuntu 24.04 Live iso image and a very old live iso image from 2017 called GParted live. In Gparted live iso, --pinentry-mode loopback caches the passphrase but not in Kubuntu live iso. Edit 3: I have tested in Kubuntu 22.04, 23.10 and 24.04 using https://distrosea.com and gpg --pinentry-mode loopback symmetric decryption does indeed not cache the passphrase except 22.04. And now the boring details: In Kubuntu 22.04, I used to use these commands to create an encrypted file from stdin and to decrypt it: gpg --pinentry-mode loopback --output out.gpg --symmetric - to encrypt gpg --pinentry-mode loopback -qd out.gpg to decrypt. While in a terminal session, the decryption command used to ask for the passphrase once for a certain time and I don't remember I did anything to get this behavior. Now I have upgraded to Kubuntu 24.04 (by fully erasing the disk). But now, the decryption command above always asks for the passphrase in the same terminal session. If I remove --pinentry-mode loopback, then the pinentry-qt dialog kicks and finally the decryption command stops asking for the passphrase for subsequent decryption commands with --pinentry-mode loopback. So pinentry-qt correctly caches the passphrase but any subsequent--pinentry-mode loopback command requires a passphrase input with pinentry-qt in order not ask for the passphrase again. I installed pinentry-tty and set the config in ~/.gnupg/gpg-agent.conf to: pinentry-program /usr/bin/pinentry-tty and reloading the agent by: gpg-connect-agent reloadagent /bye. This actually solves my problem by decrypting without using --pinentry-mode loopback. But what I want is the old (no config) behavior so I can get rid of updating all my scripts.
