There is no possibility to delete data on your own, but if the maximum is reached, as we wrote earlier, the oldest data is automatically deleted and new ones are written.
Therefore, the application continues to work even when the maximum is reached.
If you have any problem, then it is related to something else, and not with the achievement of the maximum data. Therefore, describe the problem in more detail, and also indicate your login and ID (IMEI) of the unit(s) with which the problem arose.
You can write data here or send a description of the problem and data at email@example.com
