When switching accounts there's some weird behavior if global settings are switched off (both accounts have their own settings). After switch all the settings are either set back to default or partially changed.

For example one time it changed text color to black against black background so it was very difficult to navigate the app to change it back to normal (I could only see black). Sometimes it still shows the correct setting on the settings menu but I have to reset it to the same value in order to make it effective.

It would be useful to also have a safety feature on the app that doesn't let text color ever be too similar to background color regardless of the theme settings. I don't think there's any use case for all text to be invisible in the app.
