Try this link. It only contains this week's payment information. It still loads slower than Google Sheets for me, but it is a bit better.
Can confirm, it loads faster for me but it does not load as fast as Google Sheets (understandably as they are a smaller scale company). While I haven't messed around with self hosting, I'll eventually try to host the software and try to see if there is a performance increase in loading the original file. Can't promise exactly when but I'll add it to my to-do list.
I've ran into a lot of issues trying to create this today though - I would make an edit, and CryptPad would be stuck on "Editing" for a few minutes trying to save my changes. This happened on really simple edits as well (just changing the value in one cell) which made it really frustrating to use. Have you ever encountered this?
That's odd - I've never had that issue while working on the platform. In the beginning it did had some hiccups, but considering that the sheet you've posted is simple regarding both formatting and content, I see no reason for it to had such cumbersome behavior. I've just tried pasting and editing some sheets that I had on my account and the experience was clean and responsive. The last time that such issue was reported on the CryptPad forum was on 4th of December 2022[1] but sadly the user never replied to the staff to troubleshoot his problem... I'll be on the lookout for such issue during this week and I'll report you if I find any of them. Let's hope next week while updating the sheet you won't find such nasty behavior again...
