Dashboard Tiles not refreshing with SSAS datasource behind

We have a dashboard where we pined many tiles from a report who he have a SSAS connection for datasource. Unfortunately, when the dataset is updated, the dashbord never refresh by itself. We must refresh it manually each time even if we wait 10 minutes.

Otherwise if we use the pinning a live tile, the refresh work. But, we lost some functionnality like mobile visual and link pour each pined tiles.

To make sure is a ssas connection problem we have created 3 tests situation.

first one, we create a Power Bi with a embed dummy database (no datasource connection) with a mesure contain a now() value. When we pined this mesure, the refresh work.

second, we create a Power Bi with a sql database connection with a mesure contain a now() value. When we pined this mesure, the refresh work.

The last one, we create a Power Bi with a SSAS connection with a mesure contain a now() value. When we pined this mesure, the refresh work doesn't work.

Please note, the tests never use data from database just the created mesure contain now().

we thought is a gateway problem but the pined lives pages work and the manually also.

We found this documentation :

Tile refresh
Power BI maintains a cache for every tile visual on your dashboards and proactively updates the tile caches when data changes. In other words, tile refresh happens automatically following a data refresh. This is true for both, scheduled and on-demand refresh operations.

But this fact doesn't work for us with a SSAS connection.

Some suggestions ?
