SSRS 2016 Mobile Reports - Error displaying reports on mobile phones

We have 5 reports that we need to access on our mobile phones using the Power BI Mobile App on Android but we are getting the error "Error Occurred, please try again later" on 4 of the reports. The one report that is displaying is the report that has the smallest dataset which is around 200 rows and takes 3 seconds to render. The longest running report for the other 4 reports is 14 seconds on the SSRS 2016 web portal.The biggest dataset I have is around 22000 rows and we have around 5 datasets per report but the total number of rows returned is less than 100 000 rows per report for all the reports. Is there also a limitation on the data size?
