We are aware of the work mode issue that some users are reporting and hope to address it soon. The aircraft should be put in Normal mode for mapping use. It looks like you are using 5.4.2 which is good.
The support for the Mini 2 is very new and it seems like there are some things that still don't work like the rest of the DJI aircraft. They might eventually get fixed in firmware or an SDK update but we will see what we can do in the meantime.
Note: That iOS device has an A9 processor, which should at least mostly work. We have been recommending the use of an A10 processor or better for a while now.
