encountering regular issues with sheets failing to save/load


Is this a symptom of some sort of data limit? We have a team sheet that has a lot of data (I'm not sure how many rows, since it's not currently loading, but it's 2,000+ with around a dozen columns) and for the past 2-3 months, we've encountered issues on a nearly day to day basis (it's usually the worst on Monday and in the mornings) with the sheet and associated reports failing to load or failing to save if they were previously open.

Has anyone else encountered this level of loading/saving issues, and how did you resolve?
