I converted my SIM to an eSIM and now Textra shows the dual SIM toggle even though the SIM is turned off in system settings. It is very annoying sending a message the first time in every conversation since that SIM change only to realize it didn't send because the conversation is still on the old (and turned off in system settings) SIM for some reason. It's also too easy to accidentally toggle back to the old, disabled one after toggling to the new one.
