I’m happy with my invoices and reports as they are. (I know, a rare comment.) But I have not set a base currency and do not have multi-currency enabled. I just have a simple $ set as the currency prefix. I still have that setting available to me because I started before that setting disappeared.
When I experimented with setting a base currency, I did not like the USD$ symbology on everything. It was unnecessary clutter. Is there any way to avoid that if base currency is specified?
