Oh FFS they sent these out with that old FW !  :palm:

We know about some of your observations and 1.1.3.1 is being tested however not available to the public just yet.

Jep, in fact, there is no FW available for download yet whatsoever. Not even the one it came with.

Actually it is 1.1.3.1 (12 March) - on the China site- Use Edge browser with automatic translation. - https://www.siglent.com/download/firmware/?ProId=96
I'm using it for about two month without problems and solved two major bugs ( arched waveform at maximum zoom and scope lock when using PSSR function in Power Analisys)

Later edit:

Reported bugs checked in 1.1.3.1

1. yes the FFT screen update slows down for 2 seconds when menu is activated (even is embeded or floating). Tolerable, not an issue.
2. explained by Veteran68
3. probe check detect correctly attenuation setting.
4. yes in decode menu the label setting does not appear.
5. N/A

BreakingOhmsLaw:
I found something else that someone might try to reproduce:
It reliably does not decode the (7 bit) I²C addresses 0x78 (= 1111000 ) through 0x7B ( 1111011). So, these are all addresses starting with a "11110" pattern.

Test setup:
 - I have an STM32 MCU trying to write a byte to the addresses 0x00 through 0x7F.
 - Voltage threshold for SDA / SCL at 1,5V, 4K7 pullup resistors to 3.3Volt.

0x00 to 0x77 works fine, 0x78 to 0x7C fails, 0x7D, 0x7E 0x7F work fine again.

ZigmundRat:
I just received my SDS1104X HD (from reputable US reseller) and have now spent a little bit of time getting familiar. Liking it so far. I have not tried to replicate any reported bugs as of yet. Mine came with 1.0.7.2 firmware, which seems quite old. I’m waiting to see when the next official update is released before worrying about other updates or chasing bugs. Unfortunately I can’t help right now with your I2C address issue, but will be watching.

I was a bit disappointed to see there is no NTP option in the network settings. I sort of assumed it would be there given the 800X support. I know it’s been mentioned before, but adding my vote to include this option in the future.

NTP was never considered for 1kX HD as it already has a RTC, unlike the 800X HD series.

ZigmundRat:
Presence of an RTC does not necessarily obviate the use of NTP (SNTP)  :)

In this case I would grant that there are not many use cases where ongoing resynchronization would be required, and that this is more of a convenience item - at least as long as the RTC drift is reasonable. If you are trying to match up scope captured events and other external data/event data then such synchronization may be useful, but I have no definitive use case.
