I'm dead, right?

My game was refusing to connect, giving a connection error. I tried closing stuff, reopening, restarting my phone, everything I could. The final solution I saw was uninstall everything and reinstall it.

I did that. I tried to recover my data using an Apple account. No dice. I tried using my Nintendo account. No dice.

Was my stuff all local? Is it gone forever? I use my account to supplement my partner and trade with them, I didn’t really battle ever. But is all my stuff completely gone? I feel like it is.
