I have experienced this bug two times previously, so this time I decided to document my purchase of Minds+ with onchain wallet in paint.
I have marked the things that I find importand and which buttons I pushed with red rectangles. I have also included the whole print screen in case I've missed important details. So you have timestamps for all except the second image wich I managed to lose the first one of so I had to make new later.
