Recording Date not saving/updating

Hi, I'm already a long time a happy daily and 4 season user of my K2 camera system on my Honda Super Blackbird. :-) Since the update of the app I don't have access to my camerafiles and configuration settings anymore. The app always mentioned that there's no wifi connection with my camera. But I have wifi connection to the camera with my smartphone and can see all the files via the internetbrowser on my phone on IP 192.168.1.254 So there is a perfect connection between the 2 devices. I have also 30 minutes ago updated the firmware 0.64 of the camera, made a new connection, reinstalled the app, but all without any results. Problem stay's the same. :-( I saw there are very short movieclips made, so the update is ok, just need to make the old settings back like before. Can you suggest any tips or hint. Am I doing something wrong or is there a bug somewere? Thx in advance for any help ;-) Kind regards Jelle PS: I use Iphone SE with IOs 13.3

I've had Frostie's modified firmware (higher bit-rate video) 0.57 and am trying to upgrade to the factory 0.64 firmware, but my K2 won't cooperate. I can't figure out what I am doing wrong. Here's what I do: 1) insert an 8 GB SD card into the K2, power on, connect through app, format card from the app. Power off bike, K2 shuts off normally. 2) remove card from K2, insert in PC, copy the "K2.bin" 0.64 firmware file to the card. It is the only file on the card. 3) insert card w/new firmware into K2, key on. K2 powers up, but the red camera icon only blinks once. Green "movie camera" and blue "WiFi" icons stay on steadily. Nothing happens. I've let it sit this way for several minutes. Nothing further happens. 4) power off bike. K2 does not shut down on its own, I have to use the physical button. 5) Remove SD card with firmware file. Either reinstall my normal card or no card, turn on bike, K2 powers up, connect through app. K2 still has 0.57 firmware. So clearly the K2 is not loading the new firmware file. What am I doing wrong? Things I've tried: 1) using other SD cards. I tried a 32 GB card and a 16 GB card. Same result. 2) using other firmware. I tried reinstalling the factory 0.57 firmware. Same result. 3) checked battery voltage. It is 13.0V with the bike not running. So, the K2 is not shutting down due to lack of power. 4) tried all of the above with engine running, to ensure plenty of power. Same result.

Is it possible that a multiple select for the transfer of video files via WiFi could be added? It would mean I can set it to download the required files during a journey - I always want the front and rear videos at least and at the moment each has to be selected and downloaded separately.
