I am running the Mac version (M3 chip) and it won't stay connected. I recently updated the binder and realized I had to do it in developer mode (I had stopped running developer on my new remarkable because the cal sync didn't seem to need it in one of the last updates). I realized I can't get the password without developer mode. SO, turned that back on. I had to use the cord the sync in binder, would not connect wifi (I used to use exclusively wifi connection to do this) and now, I can't get the newest cal sync to push to device without a cord. It won't connect through wifi, and honestly, connecting through a cord to get it to sync is just too time consuming. I pulled away from cal sync and was using generic planner until I could get it to behave. Now back to not behaving. I just don't have 2 hours every day to try to get it to load.
