If you don't have YouTube channel, just upload any platform (e.g. Facebook, Twitter, etc.). It depends how many days to approve your speedrun but me it just 5 days.

I'm speedrunning on Minecraft Bedrock with a map Parkour Spiral with time of 26 minutes and I need to submit it but it is okay leave blank on "splits i/o" section? I don't know if it accepted or rejected my speedrun because I leave blank it because I'm using mobile phone.

I already signed up with Google account but don't know what kind of file can upload in splits.io?

It is OK leave it blank? But without an timer and I'll timestamp it on description like: Start: 0:36 Finish: 28:09

If I accidentally died and respawn in my spawn point in Minecraft, can I still submit my speedrun?

For example, in the Hielke map Parkour Pyramid if I accidentally fall in lava or in high place and it respawn me at spawn point. I don't sure if the speedrun need to stop or continue speedrunning if I died.

Submitted an run that contains video edit while entering nether portal which portal spawn at fortress, bastion, etc. is now called fake.
