Intermittant connection loss with choices fields and sharepoint

[kanchan_bankoti]

We faced this issue where running apps stopped working suddenly from time to time and the issue behind it was sudden connection loss to sharepoint lists and also sometimes connection to the list is intact but 'choices' fields do not populate values.
In both the cases we just refreshed the data source or removed it and added it again to resolve the issue which is not a reliable fix.

Lately we had been reported this issue frequently with P1 priority.

Hi @kanchan_bankoti ,

Do you means that sometimes your connection with sharepoint will become invalid and your choice columns will not display correctly?

Could you show me your settings of your choice column, for example, its Items property?

I did't meet this kinf of problems before.

Please clean your browsr's cache, update browser to the latest version.

Also, making sure that your network is in good condition.

These all may affect your app's performance.

If your problem still exists, I suggest you ask for help here:
