What years of dollars are accepted in the Maldives?

From 2009 to 2022 release) the rest are in question

They officially started accepting it in 2006, but in some places they were quite reluctant to accept it since 2006. Moreover, in February-March, everything was great, but at the end of April, I arrived and they started refusing to accept it in some places: at the airport, when I was buying a SIM card from Ooreedo (they accepted it at the beginning of February), but with the second operator, I think it's called Diragu, there were even no questions, but the connection was completely awful, and they didn't accept it in a sweet shop in Male. In other places, they accepted it, including on different islands and at the resort. Also, make sure when you get change that the bills are not torn. Torn bills are not accepted.
