 In the question page the user have to select an answer and click validate. 
-Then, he sees the right answer and a modal with the explaination and the source. After this modal, he goes to the next question.

+Depends on the answer, the question result state is set either correct or incorrect.
 
 ### Custom Question
 
-At the end of every quiz, we're creating a custom question. During the creation of the quiz, we have to add :
-- type => data or calculation

+- period => the period selected for the calcul  
+- timestep => the interval of the calcul (Day, Month, Year)  
 We get all this information to determine the custom question (All information are in the quizEntity.json). Depending of the question type, the system calcul a maximum or an average data. 
 Then, he generate two randoms answers following the right answer. 
 
+A user can stop during a quiz and picks up where he left off. To define where the user left off, we have to check if at least one of the question result status is unlocked.

+## Troubleshooting when asking for refresh token
+
+When a token expires, the konnector will encounter an error when fetching user data, leading to a refresh token request.
+
+Since refresh token requests restart the Konnector, it was decided to add the ```usage_point_id``` into the start fields when asking for a refresh token (see line 97).
+
+!!! info "restart to refresh token"
+    Line 85: ```await cozyClient.fetchJSON(
+            'POST',
+            `/accounts/enedisgrandlyon/${accountId}/refresh`
+          )```
+
+    Line 97: ```fields.usage_point_id = usage_point_id```
+
+    Line 98: ```return start(fields, cozyParameters, false)```
+
+In fact the usage_point_id still remains in the account collection, but on restart, the konnector loses ```this._account``` context leading to an error when searching for usage_point_id in account.
