You mean like with a new nostr nsec? No, I have not tried that. Would be a bit tedious to recreate all chats and group memberships with a new nsec. But, I could of course just launch it with a new nsec and do nothing. Assuming you are curious about the OOM. A hint is that it doesn't eat memory ad infinitum after start if I click a chat. But now when I think about it, it does so after some activity in the group. It's been difficult to convert people, and nowadays they use whatsapp mostly again. So, I forgot that it sometimes OOMs in chats as well.
