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

Its okay to leave the section splits.io blank. There will be no problem when you upload it to the platform you want. You can leave split.io blank don't worry too much. 🙂
