Recording Conflict - clarification please

Thank you for your help Sara! But no, I am not asking about DVR capability on the Xumo Stream Box. I know the box doesn't have the capability to store content locally, like traditional DVR service. Now TV via the Xumo Stream Box does have the capability to record programs to the cloud, up to 20 hours. I do it almost daily. My question was about the specific rules for how you can use that 20 hours. Here's the question again:

"According to the documentation, there is a 20 hour maximum storage limit. But even though I am well within that limit, sometimes I get “Recording Conflict” alert messages that say I’ve exceeded the maximum number of recordings. That maximum number appears to be 2, BUT it also seems to be dependent on the time of day. For example, if I try to record 2 shows at 9:00, no problem. If I try to add a third show at 9:00, I get the Recording Conflict alert. But if I have 2 shows set to record at 9:00 and then add a third show at 10:00, it works. I haven’t gone through the process of experimenting to find out how many recordings are allowed across different times, so I’d like to know what the official rules are for this. So what are the restrictions/rules for recording multiple shows across different times of day? For example, can I schedule to record 4,5,6, etc. shows as long as they are at different times of day? Or 2 at one time of day, 2 at another time of day, etc. to the maximum whatever that is?"
