Garmin tacx disconnecting frequently and loss of data

Dear all,

I have the following setup:

Last version of garmin training on my Huawei p30 pro and last version updated on my Tacx Flow. They are connected with bluetooth.

When I start a race (Col du telegraphe) It started disconnecting a lot (100times) but only during the climb. It says that I need to continue to pedal in order to continue the race.

The disconnecting can last between 1 and 20 seconds. It its quite horrifying.

I tried to manually pause the race and continue but it doesn't change anything

I tried to have the smartphone closer to the tacx flow but it doesnt change a thing

Anyways I did finish that race painfully, at it end I clicked on save and then... the race never saved

I closed the app Garmin tacx and opened it again, the result of the race appeatred on a pop-up, asking if I wanted to save them. I clicked on yes agazin but nothing was saved.

Could you help me please to;

Fix the connection issue

Help me to find back the file

Many thanks for your help.

Kind regards,
