Current Behavior

• Entering \ in the instance field causes \ error
• The URL becomes malformed: \

Expected Behavior

• The plugin should automatically strip any protocol prefix from the instance URL
• Clear guidance should be provided about the expected format

2. Enter \ in the Instance field
3. Try to sync or update tasks
4. Observe DNS resolution error in console

Environment
