How to activate REM disabled?

after using REMNOTE on my iphone, many of the REMs created were disabled
how REMs are activated??


I have about 300 REM deactivated

Hi there. This sounds like a bug of some sort to me. You can submit a bug report on the official Github issue tracker.
Meanwhile, the only way to reactivate these cards is manually – by zooming into the rems one after the other and then toggling them on/off from the Cards icon in the bottom toolbar (left-most).
