What usually works for me is checking the M-Pesa app or USSD menu to generate a mini statement, then taking a screenshot to show the transaction. Sometimes it takes a few hours for confirmations to hit, especially on busy days. On a side note, if you’re exploring new platforms, some sites even let you get free cryptocurrency just for trying out small deposits or completing simple tasks, which can be a nice safety net while you wait for your main transaction to go through.
