Very long load times on android

Operating system

Android

Joplin version

3.0.8

What issue do you have?

From the time I tap the Joplin icon to the time it opens, it takes at least 7 seconds to open each and every time. Is there a way to speed it up? I tried searching this topic but I didn't come up with anything. I've tried clearing the cache, turning off bio metrics, reinstalling the app but nothing changes the startup time. My device is a Z fold 4. Thanks in advance.

Do you have encryption enabled? And if you go in the encryption screen, are there multiple keys?

Hello Laurent,
I just checked my config on the phone and I have multiple master keys. What this means? How to remove obsolete keys?
TIA
