Also, if you get your mining rewards send to your jaxx wallet. But Jaxx cant handle those transactions with so many outputs. I have experienced it first hand. it keeps crashing and initializing.
You should forward your mining rewards to a wallet like Zcash4win, to a new adress.
Jax is convenient for having some of you zec readily available on your phone e.g.
Edit: Ah I didn’t see you had only one transaction on that adress.
