What does that have to do with solving issues.
Here is one possible solution. If the OP reads the Blink FAQ’s they might read if XT cameras work with the new Sync 2 module. And if the XT camera is connected to the sync 2 module it might retain the grandfathered cloud storage.
So supposedly if the OP bought a Sync 2 module and moved the desired camera(s) to it they might be able to establish a desire Sync 2 schedule.
Of course the OP would have to read the Blink information to see if this is true and maybe wait for a sale on Sync 2’s.
