Can I use joint account statements for a non-O 90-day visa application in the UK?

When applying for a non O 90-day visa in the UK, there are mixed opinions about the use of joint bank account statements. One commenter advises that only individual statements should be used, while another suggests contacting the RTE London office for clarification, noting that if a joint account is used, the financial requirement may need to be doubled. A third commenter mentioned that they successfully used a joint statement previously, meeting the required financial balance.
