I got an error like "TypeError: null is not an object (evaluating 'this.$2H.get_$99')"  when i opened quote form on Mobile Apps.  

I check all fields on quote form and It was understood that the error was due to a count of available tabs on phone. Please check count of available tabs on form. There ara some iimitations on CRM Phone App.

To optimize performance on mobile devices, the number of objects is limited to 5 tabs or 75 fields and 10 subgrids.
