Checked for duplicates?

• [X] This issue is not a duplicate

Does it also happen in the desktop version?

• [ ] This bug does not occur in the latest version of Anki Desktop

What are the steps to reproduce this bug?

• Connect to Internet with Wi-Fi (ex: from home) with your phone
• Synchronize the deck in Ankidroid
• Leave to a place where the Wi-Fi hotspot is not reachable
• Let the Wi-Fi enabled on the phone
• Start reviewing
• An endless and unclosable "Processing…" ("Traitement…" in French) popup is displayed
• Even after stopping/killing Ankidroid, disabling Wi-Fi and re-opening Ankidroid, it is not possible to review because of this popup

NB: automatic sync is disabled

Only solution:

• Get Internet access from the phone.
• The popup automatically closes.
• Review one card.
• Disable Wi-Fi
• Continue the review

Expected behaviour

• The review should not be blocked forever if Internet access is not available
• If Ankidroid is restarted and Wi-Fi / mobile connection is disabled, there should be no "Processing" popup related to Internet access.

(Optional) Anything else you want to share?

It happens frequently when I use Ankidroid on an old phone that do not have any SIM card when I go running. I synchronize before leaving home, then if I forget to disable the Wi-Fi before leaving, then when I'm outside the only way to review is to:

• use my main (larger) phone as a Wi-Fi hotspot
• connect my old phone to it.
• review a card
• disable the Wi-Fi

Research

• [X] I have checked the manual and the FAQ and could not find a solution to my issue
