Hi. Just opened the app & it automatically upgraded the firmware now to 7.29. Now, when I connect, & try and take a 1s exposure & then another a few senconds later, the 1st exposure works but the 2nd just hangs,eventually receiving an "exposure failed" alert. Using an Iphone Xr & Canon 550d as main imaging camera. Please help as cannot use the ASIAR now. Also, the image count on the dslr now flashes very quickly which it didn't previously. If I switch off the ASIAIR & then reconnect, again I get 1 exposure & the issue reappears.
