Updates and changes required on existing native Android & IOS app -- 2

App build:
Apple: Swift / Objective C
Android: java (Android studio)

App shows user website profile data and has minimal functionality.
Three screens need some changes and some in-app functionality changed to simply open webpage.
Most changes already exist in live version but I have lost latest source files so these changes required to get source is same as current live version.

1. My Pledges screen - 8 changes
2. Tracking screen - 5 changes
3. My Profile screen - 3 changes
4. Donate screen APK only - 2 items link to website as per IPA
5. Reset Password: link to reset password website url

Detailed instructions and screenshots supplied.

I require accurate error free work and good communication.
No upfront payment but milestones released immediately upon each completion
Milestones:
1. 30% after supply of APK and IPA for testing
2. 40% after all bugs complete and 100%
3. 30% when available in App Store & play store (I have profile ready) and source supplied.
