Bug: share feature and restore purchases not working

Expected behavior

I expected to share the info and the audio file of the music track I was listening successfully with a friend
And also I expect that when I click on restore purchase feature, I should see another screen that will guide me on how to restore my purchase

Actual behavior

When I clicked on the share botton , there was no response and when I try sharing the track that was playing, I was asked what I want to share - the now playing info or the audio file. When I clicked on each of them, there was no response.
And also When I clicked on the restore purchase, nothing displayed. No action was taking by the app, thus couldn't restore purchase.

How to reproduce

• download the current version ( 2.0.4) from google play store, install and run the app.
• from genres, select any folder that has music files. In front of each track is a 3 doted lines, click the 3 dots in front of any track you wish to share, then select share from the drop down list.
• another way to see the bug is, play any track of choice, click on the 3 dots at the top right hand side, then click on share,
• when asked what you want to share, select any of the 2 options that is now playing info or the audio file.

For the restore purchases feature,

• download shuttle music player version 2.0.4 from Google play store and version 2/0.5-beta2 from https://github.com/timusus/Shuttle/releases/tag/v2.0.5-beta2

• install and then click on the launcher to launch the app

• click on the 3 small horizontal line at the to left hand side to access the menu, then from the new window, click on support

• Then click on restore purchases. Then you'll see that there wouldn't be any response, thus, the bug

• Browser: shuttle music player version 2.0.4 and v2.0.5-beta2

• Operating system: android 5.1.1 lollipop. Infinix hot 3 LTE
